This is my ideal next update but they are too close to worry about upgrading for now. Would be a waste of money. Think I'll buy a better motherboard. My current ASUS P79 pro is just not big enough to get 4-sli on so I settle for 2-sli. Still - takes 64GB DDR3 which works amazingly well with this CPU. Never had a minutes problem with it.

damn, the 4th gen 930K makes the 3rd gen look like something from the 20th century..... DAYUM!

Definitely a mistake! Will get this fixed up, thanks for the heads up
