I got a couple X99 setups, but they are on the highest end of X99. Asus X99 WS-10G and an Asus X99 Deluxe II, both were new when I bought them. CPU's I have a few 5930K, couple E5-1660v3 (unlocked multi, equal to 5960X), and then a couple ES chips. Got memory kits circa X99 as well too, all higher end. What's your budget?
