It has been years since I have built a pc.Back then there were no multicore processors so you just bought the fastest thing supported by your board.Well after years of using junk prebuilts I decided to build my next one myself.Now my problem. I bought a gigabyte GA-M68M-S2P board and went to there site to see what the fastest supported processor was.I can't make hide nor hair of there list.This brings me to my problem.Likely simple for the pros here to answer.What is the fastest processor with the most cores supported by the above mentioned board.

I hope to also upgrade to the max supported ddr2 ram which I believe to be
8gb but would like your input on which speed would go best with the processor.

Any help you can offer an old timer would be great.
