i currently have a dual-core chip on this motherboard and would like to update to a quad-core. my question is will i experience any problems with the new quad core chips like the q9400 with this motherboard? will that chip be 100% compatible or should i get a new motherboard?
You would likely need to update your BIOS, though I'm not 100% sure P965 supports 45nm. Check the ASUS website to see if the newer quads are supported, if not, then you may need to upgrade, or get a Q6600. Hope that helps.
