First of all, this is the best am2 mobo money can buy, if you got the money this is the board to get.
I havn't personally seen or used one but I have heard some really great things about it since it has a lot of innovative features...
There were a few issues early on:
I have read that there are some errors with processor and memory lcd posts as well as raid configuration problems but its all fixed now. At initial release there were a ton of doa mobo's but it's all been fixed now as well.
The motherboard itself is the most advanced motherboard to date with a ton of new and innovative features that top all the other motherboard manufacturers. If your looking for some really nice features this board is the way to go. It comes with the largest mobo manuel ever (over 100 pages)very well documented. Also it's really good at overclocking. The heat pipe is very efficient.
People often refer to this board as being the most well setup:
-After market heatsinks won't interfer/touch any other components.
-3 pci slots, and two of them accessable even if your using sli graphics cards that take up 2 slots.
-6 sata ports (insane)
-Up to 8 gigs memory for vista
-And it comes with 3dmark 06 advanced
