The list of components i've compiled is as follows:
-A corsair 4000D airflow case
-Ryzen 5 3600 (might be a slight bottleneck, but i have a 3900X, which is basically the same but double the cores and it barely gets any load during gaming)
-BeQuiet Pure Rock 2 cooler
-Corsair Vengeance LPX DDR4 2x8gb 3600mhz
-BeQuiet System Power 9 CM 600W
-ASUS Prime B550-M A
-3060 TI, manufacturer doesn't really matter
-2TB M.2 PCIe 4.0 SSD (haven't decided on a manufacturer yet, but likely to be crucial, corsair or WD)
for context, she's going to be using a 1440p 144hz monitor and she's planning to play games like Warzone or some of the newer CoD games
i have built multiple PCs roughly in this region of performance before, and they've run great so far.
appreciate any suggestions!
For the M2 drive, PCIE 4.0 is wasted money over 3.0. I've actually "downgraded". In my system over my last re-install, intending on moving all my games over to the pcie4 drive after getting the old system wiped off it. For the time being I'm running everything on the pcie3. Well, now I'm just committed to it. That was 6 months ago. I honestly can't tell the difference between a game on the pcie3 and pcie4 drive.
The Crucial P3 2tb is less than 100 USD, ~85 GBP, and looks like it's about 108 EUR on Amazon FR and DE. It's a fantastic drive.
For the CPU cooler... why not just go with the stock AMD fan?
Also, I see in another comment you've said you went with Nvidia for raytracing. No one is going to be doing raytracing on 1440p 144hz with a 3060ti at over 60fps. For the budget you have here, forget about Ray tracing, and just pick a GPU that has the best raw rasterization performance. That maybe AMD or Nvidia depending on your local market prices, but if you can squeeze a rx6800 into the budget that would be a massive boost in performance.
