This chipset will ROCK! Not only will the performance be really good, but the price will be affordable. I can't wait to get my hands on it.
Before the release of KT266, there were reports that it would perform poorly and others speculate that it might be able to deliver performance equivalent to 760 (when the KT266 was close to being released). The KT266 board I have is definitely on par with 760 boards. A friend of mine has the A7M266 and we both get the same performance in real world performance.
