Gaming/simulation Computer Advice

Budget (including currency): 1800 (CHF)

Country: Switzerland

Games, programs or workloads that it will be used for: CPU intensive games & Numerical simulations

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): I am looking at buying a new PC from PC-Specialist, though I am open to building it myself. I currently have the following components in mind:

CPU: AMD 7900X

Motherboard: Asus Prime X670P-Wifi

RAM: Corsair Vengeance (2x16) GB 5200 DDR5

GPU: I intend to continue using my current(1070Ti) GPU and upgrade that at a later date

Storage: 2TB-Solidigm P41+ Gen4 M.2 (4125MB/sR, 3325 MB/sW)

PSU: Corsair 750 modular 80 Plus Gold

CPU-Cooler: Frostflow 200-series (250W TDP)

I was wondering if there are better/more power efficient alternatives to some of these components, or whether I have overlooked anything in this build. Any advice is appreciated.

Consider a 360 AIO.

Consider an 850W PSU just to provide more options when it comes time to upgrade the GPU.

Did you cost an i9-13900K system? It would offer better performance and real world power consumption is similar to AMD.

I thought about going for watercooling, but it seemed a bit daunting, and I dont know if the cooling is actually much better than equally priced air coolers. The air cooler I picked is around 48 Francs, whereas a similar TDP 360 AIO is 64 Francs. So the cost difference is minor. My main concern is upgradability, I have heard that AIO's are much more difficult to change than aircoolers. Im not 100% sure about this tho.

850W PSU seems reasonable, especially given the power draw of alot of gpus nowadays.

I did look at the i9-13900K CPU, Digitec has the i9 at 600 CHF and the 7900K at 480 CHF (27% more expensive). The power draw of the i9 seems to be a bit (~15%) higher as well, at least in the benchmark I looked at, while performance gain seems relatively small.
