Basically I'm have issues finding a CPU for the ASRock Fatality X99 Prof. i7. I was originally gonna go with the 6800k, but later found out that the 6700k was better but now I'm not even sure. I just want to know what the most practical CPU is for this MB. All I want to do is play games like crysis, Disonored, Tomb Raider, and other games like that...help me please lol.
