So Ivy Bridge IGP does work? What kernel and Xorg versions are you using? I just built a new system with a i3-3220 and B75 chipset. I threw in a GT520, assuming IvyBridge IGP wasn't quite ready for prime time. The system is pulling about 50W at idle with a ITB drive, but maybe I should pull the GT520 out and install something more bleeding edge than ubuntu 12.04, kernel 3.2.0 and whatever Xorg that comes with?
