If it's an Asus board that you want, there's the P4B533 and there's the P4S533. Both seem to be good boards, the first being based on the Intel i845e chipset and the other on the SiS 645DX. I personally think that there are better boards for the money out there (Gigabyte 8SRX) but that's just my opinion. If you want RDRAM, there's a couple of boards that are out with the new i850 chipset. I haven't really considered it myself because the motherboard was too expensive. I think the money should be better spent for something more useful like a good case/PSU and maybe a better monitor. If only I hadn't a car to buy to go to work... well my parts arrive next week so I'll still build it...
