I'm gonna pair my board with a core 2 duo and table the Quads until the X38 chipset. I've got two Q6600's, a G0 & a B3, both of which heats up the power circuitry far too easily. I think the 680i chipset simply isn't up to par for overclocking quad cores. Stock or a little above but not serious overclocking. Suxs because I already have a decent 680i board with the Abit IN9 32-Max.

I've tried the evga a1/t1 boards and did vdroop mod. It's a nice, fairly simple board, but it struggled to clock my quads as well, though easier to setup than the DFI.
