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!
