I have had a KT266a motherboard myself and the benchmarks I did on it were definitely an improvement over the KT266. The board I had was the ASUS brand by the way. I upped myself to the A7V333 board however, and noticed quite an improvement on my benchmarks (memory and the like). Although the A7V333 isn't very good for overclocking the FSB from what I could tell. It's been all around stable for me even running my memory using the highest BIOS settings. I haven't had a chance to play around with the Nforce2 or Nforce series of chipsets, so I can't give any feedback on that other than from what I've seen on the NET, the Nforce2 seems to fair very well against the KT333 chipset, plus improves above the KT266a chipset. Good luck finding what fits best for you
