I agree above 60fps matters. I am running with the AMD FX 8350, 8gb ram, and the Zotac GTX 970 I just installed today. I've got the Seiki 39 inch 4k monitor, but it is only at 30 hz refresh for 4k, so I run 1920 x 1080 with 120 hz refresh, and Fraps is showing me around 95 fps. The game is so fluid. I had an AMD 6 core processor and the AMD Radeon R9 270x and I was only getting in the 40's for fps.
