Hi, I have a Demision E520 with the E520 MBO OWG864 (Motherboard ID: DM061), Intel Broadwater G965 chipset (Supported FSB Speeds -  FSB533, FSB800, FSB1066) current cpu - DualCore Intel Pentium D 945. I want to upgrade my cpu to a core2duo E6600 or E6700. The 945 is a 800 mhz graded cpu and the E6600 is 1066. Also, what core2duo cpu's can I upgrade to? I assume any one that is 65nm and FSB533, FSB800, FSB1066.

I have upgraded the psu to a zalman 600w, gpu to HD3870, 2gb x 2 ram and a HT Omega Claro2 sound card. OS is  vista ultimate x64.

Thanks for the help!
