Its going on a gigabyte p35c-ds3r running stock at the moment but I believe you can overclock this CPU pretty good. Its my secondary rig running MacOS via EFI-X but I have an XP drive to test the OC. Also whats a bulletproof OC and temp range for these CPUs with some tips on BIOS config if poss. Its in a Lian Li V2000 so I can take a cooler as high as a TRUE but im not wanting to spend TRUE money. Thanks guys
