He has the wrong memory doesnt he? 4200? The 6600 cpu is 800mhz fsb. 800mhz memory is pc6400. Choosing the gigabyte board he can o/c that 6600 to the moon and strap 1:1 with better then 6400 memory right? Or did I miss something here? I'm sort of in the same endeavor. Slap me if my facts arnt straight.
