There are a number of articles around the web. I found this one at XbitLabs informative:

To me its good news because it really doesn't outperform its socket 939 counterparts by much which means I won't have to go buy a new CPU/mobo/RAM.

Unfortunately I don't know much about DDR2 so I'm not sure how much faster RAM than you can get than DDR800 with 4-4-4 timings, but I know there a lot of DDR that can get more bandwidth than DDR400 with 2-2-2 timings.

So who's gonna upgrade?
