Im building a computer later this week, and I've been looking at the:
Abit KX7-333 Via KT333/VT8233A ATA133/DDR333 SoA
Now i don't know if people are having any trouble with these boards, but from reading up on it, it looks ok. it supports all the up-to-date features, and 2200+ SoA.
As for your processor, I would go for the 2000+ (1.67Ghz)as the price difference (here at least) doesn't justify the minor jump in speed.
Wait until you get a few more posts before splashing out though, other people will have different views, and may have had bad experiences with the above. It should be a good games machine, however, multiprocessor support might be a good idea if your running a server.
