I've had an A7M266 since March and I like it quite a bit. Once I got a few hardware kinks worked out, it has performed like a champ and is quite fast.
Hardware snafu #1 - Avoid the Netgear FA-311 and FA-312 network cards with this board. This actually is starting to appear to be an issue with all AMD 760 boards as people such as HardOCP and forum readers over at AMDMB.com have reported the problem on Epox, Abit, Asus, and MSI 760 based boards. What happens is that the NIC seems to interfere with soft reboots. If you try to reboot from Windows, DOS, or from the BIOS setup utility, the system will hang. It can be reset with the button on the front of the computer, but that's not the preferred way of doing it. Switching PCI slots doesn't fix the problem either and there haven't been any BIOS fixes that I've heard of. Using a 3Com, Dlink, Linksys, or even a Netgear FA-310 NIC avoids the problem.
Point #2- Though many people can use SBLive! cards with this board without issue (or fixed any problems with BIOS and driver updates), I ran into some hard drive corruption problems with a SBlive Platinum 5.1 that weren't fixed by any of the patches (or changing PCI slots). All of the issues went away when I switched to a Philips Acoustic Edge soundcard. My recommendation to people buying this board, that don't already have a soundcard, is to use the onboard sound (which ain't bad at all) or go with a Turtle Beach Santa Cruz or Philips Acoustic Edge sound card. I owned Creative Labs soundcards for over ten years, but after two weeks of trouble shooting hell (before buying the Philips) I have a hard time recommending them for use with the Via686B southbridge. I know many people have used SBlive!s with this chipset without problem, but I feel like it is skating on thin ice. Just a recommendation, but one that comes from personal experience.
