Friend of mine has it, says it's the best motherboard he's ever owned. He's pretty hard to please, and didn't like Gigabyte before winning it at the XP tour. He convinced another friend of ours to go with a Gigabyte i850 board too.
Long story short, good board.
I intalled the GA-7VTXH+, it's non-RAID baby brother with the KT266a in my backup system. Killer board. Good layout, and it's solid, dude. I popped that board in and 45 minutes later I was looking at an error-free installation of WinXP.
This is the first VIA board I've installed that I really like.
I also had a really good experience with the GA-8TX. It runs my P4 1.7GHz very nicely.
I was SOOO tempted to buy that RAID board! But I had a budget, and I stuck to it.
