I've been looking all day, and only a few sites even list the i7 (as not available). Most sites have no trace of it. Some sites sell pre-built PCs with an i7 6700K, but I don't want it bad enough to spend $900 extra and try to sell the parts I don't want.
Places not selling the 6700K... Newegg, Amazon, Allstarshop, MA Labs, Microcenter, OutletPC, SuperBiiz, NCIX, TigerDirect, BH PhotoVideo... The few sites that do list pre-orders error out if you attempt to pre-order. I wish we could get a time when they will go on sale.
