To tell you the truth I would probably get LeadTek's version, I have very high respect for their company, as they make many products (like GPS systems, video serviellence/conferencing, etc...), and have been the best quality vendor in the video card market.
I think they were one of the few vendors that included a northbridge fan.
Or maybe Abit. I just saw an article speaking of Abit's dedication to making the best overclocking boards, because they insist on nothing but the highest quality capacitators (Rubycon ones from Japan).
Alot of the problems with these boards come from the nForce 2 chipset itself, not which vendor you go with.
Benchmarks don't lie :-)
