I was wondering if anyone would know what would be faster. My home theater Pc is a Pentium D 915 OC to 3.2ghz, now the board i have it on only allows C2D with 800fsb. If i put my e6600 in it, it will turn it down to 1.8ghz@800fsb (according to gigabytes website). Will the C2D sitll be faster underclocked or will the PD thats overclocked and running at full strength? By the way, I am going to eventually change it out, I recently upgraded my gaming computer to a EE and not using the e6600 at the moment, so I dont need the "who cares buy another motherboard comments."
