Core 2 Duo E6600 "Conroe" vs Xeon 5130 Dual-Core "Woodcrest"
"Conroe" Socket LG775, "Woodcrest" Socket LG771
FSB Speed "Conroe" 1066Mhz, "Woodcrest" 1333Mhz
Clocked Speed "Conroe"@ 2.4Ghz, "Woodcrest" 2.0Ghz
In my Opinion I'd go with the E6600 Conroe Aka Core 2 Duo E6600 it's Native speed is faster, And it's on a Socket 775 which is the good.
