It's for gaming? First off, bag the Pentium 4 idea - AMD has a much better price/performance ratio. I'm a hard core gamer, and my AMD system kicks some serious a$$!
That said, while DFI makes nice boards, the FIC AU13 is the finest nForce2 board on the market, officially supporting the 400Mhz FSB of the fastest Athlon XP chips! I've installed dozens of them, and never had a single problem - indeed, I was so impressed, I replaced my prior very nice Epox 8RDA+ with one. And you can get it from newegg for ~$80!
