I've been real happy with my Gigabyte 7VTXH, i've had it for about 9 months now. It's been running with an Athlon XP 1600+(oc'd a little to 1470Mhz), 3 x 256MB OCZ PC2400 CL2.0 DDR Memory, Maxtor 40GB HD, and an ATI Radeon 7500 Video card running two monitors.
Just curious why you want KT266A, since you can get KT333 for only $20 more probably. For example, you can get the Gigabyte GA-7VRX V.2.0 , VIA KT333 5P1A3D RETAIL for $80. It has good onboard audio, ATA133, 8 USB Ports(2 on board, 6 more can be added, 4 are USB 2.0), and dual bios.
Don't get me wrong, i'm happy with my KT266A board. It's just that with the KT400 boards coming out, if you wait another week or two, you can probably get a ton of KT333 boards with Raid for under $100.
