also the crossfire on those boards is not half bad for 8x/8x... hardly a -10fps reduction off of the slightly more expensive x38/x48's that have 16x/16x.
^^ The Biostar Tpower I45 set the world record with a fsb of 725mhz. I would call that a significant improvement over a p35. Granted that was running phase change but it will still do 600mhz + on air.
