I recently built a computer (twin pcs actually) with a 2500k and this mobo:

Absolutely loving it, and Virtu in GPU-D mode is pretty nice stuff. Have my 2500k at 4.5gHz (light I know, but I'm a newbie at OCing) on stock voltage w/ air in an antec 300 illusion with an
acfz13-pro cooler.Haven't bothered to try GPU-I mode, but it seems decent enough. Inb4 z68 isn't worth it for this or that reason.
Btw, all of your links are broken, for me at least.
