With the price of 761 boards so low right now, KT266 doesnt seem like a very good option.
At Newegg.com
Rev 4 of the Gigabyte GA-7DX = $117
Biostar M7MIA-R =$112.
DFI AK76 = $105
MSI K7 Master = $130 (not at newegg, local store)
EPOX EP-8K7A = $115
Also, ASUS boards are highly overpriced with the A7V266 set to break $150 by most accounts, and for that huge lump of money, you can get feature packed boards like the SOYO K7V-Dragon.
All in all, I reccomend the EPoX board... until KT266A launches, SiS can ship more 735, and nForce finally is released you will be top dog... and besides, the performance difference between all these boards is basicly nill, and you will have yours NOW... not in a month.
