http://pcpartpicker.com/p/pTYG99 The biggest games I would be playing on this pc would be far cry 3, skyrim, or just cause 2. Can this pc handle those games?
It should be fine, maybe just more ram and your all set. (I have never played far cry so idk about that one, sry, but other than that I think it should work)
Thats a good build, it can run Fallout 4 on Medium Settings or basically most of the newly released games at probably medium settings. Fallout 4 is really demanding though but i don't think you are playing that so thats good. Even my Intel Core i7-4790k with GTX 960 drops to 20 FPS when a big explosion comes
