Put in layman's termsish, that's an AM2 Processor so you need DDR2 RAM for it, not DDR1 as 939 was happy with.
It's good because it's VERY smilar to my new build. X2 4200+: Same as me, great CPU. For some reason people will say "go 3800 or 4400, the 4200 sucks!" - but no, really, the 4200 is imo one of the best buys out there. Mobo is awesome, I'm getting the similar SE version. a 37GB Raptor will kick ass! Hence why I've bought one a 250GB Caviar is good. I already have two. would have bought a third but the site I used don't sell them, so I went with a Barracuda. X1800XT is good, I got the 1900, but it's still a fast card! Nice case, good sound, one problem: Power supply. Thermaltake 430s actually aren't that good, and you're running close to 430W with that system at peak times, I'd get something like a Seasonic or Enermax of 500W+.
