I'm looking at this board too. I don't care about overclocking, I'm just concerned about stability and compatibility (I normally buy Intel boards for that reason).
I know Chaintech's Nforce 3 150 board was one of the only Athlon 64 boards that didn't have compatibility problems with any of the RAM Tom's Hardware tried in their tests, so that's promising. It's just that I had such an awful experience with an Athlon Thunderbird on a craptastic VIA chipset that I'm REALLY scared to try another Athlon (even though I'm sure the CPU itself was never the problem).
But geez, it's $80 cheaper than an Intel 875, and the CPU is significantly more powerful at everything *I* use it for (don't do much media encoding, to put it mildly). But I don't want another experience where I'm patching the damn thing twice a week for half a year, and never get total stability and compatibility.
Chaintech DOES have the board up on their website now...it was a little creepy when they didn't earlier in the week. Dang, wish their was a review from someone about it's stability. I think I may have a 3200+ A64 in my future. I could almost get a 3400+ with the cost savings versus that Intel board.
