I bought the Chaintech board at X-mas, and I LOVE it. I have never had a board overclock so well, and the thing is rock stable. I am running mine overclocked to 300HTT (which puts my A64 3000+ at 2.7GHZ), and have had it this way for almost a month now. I also can assure you that I have no issues with my NIC (even above 250HTT).
The caveat about this board is ANYONE who overclocks it should add a fan to the chipset's heatsink (do not get rid of the stock heatsink tho, because it actually works better than most replacements). Any cheap small fan (including a vidcard one) mounted to it will work great, and I think the NIC issues above 250 are from folks who have NOT added a chipset fan.
I have heard from some who have issues with the onboard sound on this board (1 person with static, and a couple with 1 or more surround sound jack dead), so if you plan on using the onboard sound, you might want to look at the other board (or like me, just have a Soundblaster Audigy 2!).
I recommend this board wholeheartedly for pretty much anyone. Stock it is fast, stable, and cheap. Overclocked (with a chipset fan) it rockets, and is still very stable, and all for not much money.
