I am currently buying new parts to swap out and eventually have a new PC, but so far I ordered a new case (NZXT Noctis 450 white) and a new 650w power supply. I currently have a very old Radeon HD 4200 (that doesnt even work with windows 8.1 64 bit which i have) and an Athlon II 635 CPU and 4GB of DDR2 ram. I wanted to buy a new EVGA SSC GTX 960 4GB card but don't know if it will work with such an old cpu, mothermoard, and ram. I want to play GTA 5, Fallout 4, GMod, CSGO, and other games at 1080p. Please help.
