A strategy PC should stay enjoyable when the map grows and the simulation gets busy. I would choose the titles first, then balance processor, memory and graphics around the late-game workload. Buying a huge GPU is not always the useful upgrade for a crowded city or sprawling factory.
Match the screen to the graphics target, then choose the gaming mouse, UK keyboard and headset around the desk. The network plan covers the fixed PC connection.

ToggleStart with the work the PC will do
List the strategy games, map sizes, mods and the stages of play that matter. A detailed 3D city can have a substantial graphics workload, while a simulation-led factory may spend more time on CPU and memory behaviour. Turn-based games, real-time battles and city builders are not one universal benchmark. Start with the games you actually intend to keep playing.
Plan for the developed save, not only the empty opening map. Large mod collections and long-running worlds can change the resource use. I would give the tower sensible memory, choose a CPU appropriate to a gaming-first machine and allocate the graphics budget to the screen and game view. Keep old saves backed up before changing mods or versions.
| Build priority | What I would buy | Next guide |
|---|---|---|
| Best premium simulation-gaming route | The X3D gaming route belongs on a premium shortlist for the titles and saves that benefit. | Processor choices |
| Best balanced gaming route | A mainstream 16GB card preserves processor and memory spend in a strategy-focused tower. | Graphics choices |
| Best focused AM5 gaming kit | 32GB DDR5-6000 CL30 is the supported-profile route for a focused gaming tower. | Best RAM for Strategy and City-Building PCs |
Choose the processor
Cache, memory behaviour and the simulation’s implementation can matter as much as a core-count label. I would start the premium gaming route with X3D, while keeping the 9600X as the affordable AM5 option. Use evidence from the exact game and developed save before making a numerical performance promise.
The Ryzen 7 9850X3D is the premium gaming-first route. I would reserve it for a build where the CPU-side workload and a capable graphics card justify the extra spend, rather than making it the default in every gaming shopping list.
Compare the complete tower, including the monitor. Choose the less expensive AM5 route if the saved money moves the graphics card or display into the tier you actually need.
| Best for | My choice | Why it fits |
|---|---|---|
| Best premium simulation-gaming route | Ryzen 7 9850X3D | The X3D gaming route belongs on a premium shortlist for the titles and saves that benefit. |
| Best lower-cost AM5 tower | Ryzen 5 9600X | Choose six cores when the full gaming basket and monitor should stay affordable. |
| Best mixed-use strategy desktop | Ryzen 7 9700X | Eight cores support a useful gaming/work desktop without a workstation-sized CPU. |
Compare processors for this build · Understand the wider processor choices
Build an AM5 tower in PC Builder to see the PC in 3D, compare planning estimates and save your selected parts. Use the workload and setup advice here to refine the choices.
Choose the graphics route
Choose graphics for the visible scene and display. A CPU-limited simulation update and a GPU-limited city view need different upgrades. The mainstream 16GB route is my balanced start; move up when the actual visual workload earns the graphics spend.
The ASUS Dual RX 9060 XT 16GB is the value-oriented gaming route in this shortlist. The useful attraction is the combination of a mainstream card and 16GB of graphics memory, while leaving room for a good processor and the rest of the setup.
For software-led work, choose the card after the application backend. A CUDA-specific tool changes the shortlist; a gaming product name alone does not establish compatibility with a workstation or local-AI package.
| Best for | My choice | Why it fits |
|---|---|---|
| Best balanced gaming route | ASUS Dual RX 9060 XT 16GB | A mainstream 16GB card preserves processor and memory spend in a strategy-focused tower. |
| Best lower-cost NVIDIA route | MSI RTX 5060 Ti 16GB Shadow 2X OC Plus | Choose this 16GB option when the NVIDIA software/features route suits the wider machine. |
| Best heavier 3D city workload | Gigabyte RX 9070 XT Gaming OC 16GB | A higher gaming graphics tier for a demanding visual view and display arrangement. |
Compare graphics choices for this build
Use the graphics-card guide to match the screen and games, then compare like-for-like frame-rate results.
Choose memory capacity
32GB is the focused starting route; 64GB belongs to a defined larger modded or mixed desktop workload. The fact that a simulation becomes CPU-limited does not establish that adding RAM capacity beyond its use will solve it.
Corsair Vengeance 32GB DDR5-6000 CL30 is the gaming-oriented alternative when its complete price makes sense. I would choose it for a focused gaming tower that can use the profile and does not need a larger kit.
The latency specification is not a substitute for enough capacity. If a workload regularly fills 32GB, move to a suitable 64GB kit before paying extra for a tighter-timing 32GB kit.
| Best for | My choice | Why it fits |
|---|---|---|
| Focused lower-cost route | Crucial Pro 32GB DDR5-6000 | 32GB keeps a restrained first build affordable. |
| Roomier working desktop | Crucial Pro 64GB DDR5-5600 | 64GB supports a defined larger active workload. |
| Larger supported-capacity route | Corsair Vengeance RGB 96GB DDR5-6000 | 96GB is for a known need and a board that supports the exact kit. |
Choose the memory kit for this workload
Plan the RAM capacity for the work kept open together and the supported module arrangement. The profile guide covers setup once all memory is working at defaults.
Choose active storage and backup
Put games and active mod libraries on the NVMe drive and keep saves independently copied. Separate downloaded assets from irreplaceable saves. Leave room for updates and avoid changing hardware, game version and a large mod collection together if you want a clear comparison.
The Crucial P310 2TB 2280 is the capacity-first NVMe choice. I would use it for an operating system, applications and a sensible working library when the budget should remain available for the main processor or graphics decision.
Keep some free space and a separate backup. A single fast drive is convenient, but a partition on that same drive is not a second copy if the device fails.
| Best for | My choice | Why it fits |
|---|---|---|
| Budget active-drive route | Crucial P310 2TB M.2 2280 | 2TB capacity for a restrained first tower. |
| Balanced active-project route | WD_BLACK SN850X 2TB | 2TB working space for applications and active files. |
| Larger working footprint | WD_BLACK SN850X 4TB | 4TB when the real library and working data justify it. |
Compare storage for this build · Distinguish memory and storage upgrades
Choose enough working storage, then check the exact SSD format/interface. The PCIe comparison helps decide whether the speed premium serves this build.
Choose the motherboard and connections
The Gigabyte B650 Eagle AX is the standard AM5 starting board. I would buy it when its storage, networking and USB layout cover the job, then keep the rest of the budget for the processor, memory and active project drive.
Confirm CPU support on the installed BIOS and map the M.2 slots and expansion cards before adding devices. More expensive chipset branding is useful only if the extra connections have a job.
Map the devices you actually plan to connect: displays, USB equipment, storage and expansion cards. Make the CPU, board and memory a matched platform before choosing optional accessories. A thick graphics card can cover a slot that otherwise looks available.

| Starting platform | Gigabyte B650 Eagle AX | The board used in this guide’s complete configuration. |
Choose the board and useful features · Understand the connections worth buying
Read the board/platform guide and check the case’s internal connections. PCIe and M.2 sharing keeps the planned drives and expansion cards usable together.
Choose the case and cooling together
The NZXT H5 Flow 2024 is the conventional airflow-tower starting point. I would use it when straightforward assembly, accessible components and a clean desk appearance matter more than squeezing the machine into the smallest possible space.
Choose the final graphics card and cooler before signing off the layout. The case’s maximum dimensions and an installed front radiator are not independent allowances.
The Thermalright Phantom Spirit 120 SE is the other sensible twin-tower route here. I would choose between it and the Peerless Assassin using the actual basket price and fit, then set a fan curve suited to the room.
For long processing sessions, establish temperatures and fan behaviour under the application you use. A quiet idle desktop does not describe the PC while all cores are occupied.
| Best for | My choice | Why it fits |
|---|---|---|
| Starting enclosure | NZXT H5 Flow (2024) | Match the case to the whole layout and room. |
| Starting cooler | Thermalright Phantom Spirit 120 SE Black | Use the correct socket mount and installed clearance. |
Compare suitable case routes · Choose the cooler for the socket and space
Use the case-fan shortlist for the usable mounts and PWM/DC setup for the finished layout.
Choose the power supply
The Corsair RM850e 2025 is my conventional modular PSU route for a capable tower. Its role is a sensible power and cable foundation, rather than using the wattage label as a reason to spend without considering the components.
Use only the modular leads supplied for that PSU. Confirm the exact GPU recommendation and connector, and leave room for the power lead at the case panel.
| Best for | My choice | Why it fits |
|---|---|---|
| Starting configuration | Corsair RM850e (2025) | The supply used for this guide’s restrained or balanced parts basket. |
| Larger high-power tower route | be quiet! Pure Power 13 M 1000W | Choose this only when the final component power requirement and case layout need the larger supply. |
Compare the PSU routes · Understand connectors and cable fit
Match PSU load, connectors and installed space together, then keep the exact compatible cable set with the unit.

| Power supply | Corsair RM850e (2025) | Use the correct form factor and component power plan. |
| Case | NZXT H5 Flow (2024) | The complete layout’s enclosure. |
| CPU cooler | Thermalright Phantom Spirit 120 SE Black | Correct mount and fit for the chosen case. |
This is the starting basket for the route described here. Choose the alternative parts as a complete matched configuration, keeping the board, memory, cooling and power changes together. The monitor, operating system and any equipment you already own should be counted in the total purchase plan.
For the other decisions in this cluster, use the processor shortlist, the graphics shortlist and the specialist buying guide.
Assemble and set up the PC
Install the game and a known mod set, then load a representative developed save to establish the real baseline. Set the display and graphics mode independently of simulation-speed decisions. Keep saves backed up before any major game or mod update.
When a late game slows down, distinguish simulation updates from drawing the view. Reducing visual settings can identify a graphics-side limit, while a CPU-led simulation problem needs a different investigation. Upgrade for the exact title rather than assume every strategy game responds identically.
