Core 2 Duo E6400/2.13GHz,2M,1066MHz FSB L2 Cache : 1 x 2MB or Intel Pentium D 950 Presler 3.4GHz 800MHz FSB L2 Cache : 2 x 2MB I currently have the Pent D 950 in the MB.
Looks the E6400 will work and would be the better CPU http://www.intel.com/support/mothe [...] e_c2dp.htm
since the mobo does not like to overclock over 375fsb i would use a 1066 chip like a q6600 or e6600
