650 for just the card would get you something like a 1070 or a 1080 if you push the budget (or pick a different model)

my budget is anything below $650. I play games like GTA V, planning on buying the Witcher 3, CSGO, Skyrim, Rainbow Six. 1920 x 1080 for specs. I only said 1440p because if it can run 1440p on 60fps it would definitely run above 60 fps on 1080p.
