hey, i jus got my q6600 G0 and it runs fine at stock speeds. however when i try to overclock it, my pc is really unstable, even at 2.7ghz. i read around on the internet and it seems my board (p5ne-sli) is really poor at overclocking the Q6600's. i'm looking to upgrade to XFX MB-N680-ISH. anyone know how well this overclocks the quads?
