Currently I have a Dell 660s and I want to play CS:GO at 60 fps High-Medium graphics. I have watched a video on someone with a Pentium D and he put a R9 290 in it. It bottle-necked quiet a bit, but it still hit a constant 30 fps on Skyrim. So I did some research about the stock motherboard, and I don't know whether or not if I could put a GTX 950 in it... I know the 660s Case is too big for it, so I am planning to get a new case and power supply. Tell me if the GTX 950 will work and if it won't then tell me a build that I could make to replace my current one. I want the build around 450 - 600 dollars. Thank you!
