No better board than Rampage 5 Extreme on the market for X99.
All advanced users and older IT fans who have chance decide to go on ASUS X99 and at least i7-5820K.
Even people who didn't upgrade platform from 1136 period and old i7-950, Xeons, or 6 cores 980X...
They recognized good chance to get nice platform and 6 cores with 15 cache for almost same price as i7-4790K.
Special if someone do some job from time to time on PC and need advantage of 6 cores, not only games.
Who have money i7-5960X is king. I still can't get over because I missed one in October for 500e.
I planed him to keep on 4.0GHz on R5E.
