Check pricewatch for nforce boards. Just type "nforce3 250" in the motherboards category. Last time I checked, there was a chaintech and gigabyte model, both receiving mixed reviews at newegg. Another possibility is an sis 755 board, the k8s8x from asrock, which received great reviews and is only $85 at newegg. I would go with the retail boxed version of the athlon 64 and get a 3 year warranty. I just used mine for a p4, and Intel got me a new cpu in about 6 days. For memory, I would check the manufacturer's recommendations, or just go with crucial pc3200 (regular, not registered), which you can buy directly at their website.
