Re: 4930K or 4960X
I think X is for their "x-treme" edition. I would go with the 4930K. It's pretty much the same CPU but a tad slower. Still overclocks like a son of a bitch.
FX-8350 @ 4.7 cooled by H80, 32GB Mushkin Enhanced Blackline 2133, Asus Sabertooth 990FX, 2x Radeon HD 7850 2GB in X-fire, 500GB Samsung 850 Evo, 4TB Seagate, 3TB WD Black, 2x 1TB WD RED in RAID 0
