Ok, I'm building a new cpu but non of the S939 mobos seem to support DDR2 ram. Is this even a BAD thing? I've been reading but can't get a clear description of what the difference is. Same goes for S939 vs. AM2. Is there and winning combo because I'm thinking of just getting a DFI lanparty mobo that's S939 and going with PC2-800 DDR ram..... any help?
