I've had good luck with two I purchased. A 2-year old TA790GX I used in a build for my brother has proven to be a beast of an overclocker, too. I got his AMD X2 550 up to 3.7GHz at stock voltage on that board. The only bad thing with that particular board is I can't unlock the 550's severed cores on it. That CPU will unlock on two other Gigabyte boards, though. Biostar told me it's because the board has a single-plane power design, and AMD's quads require dual-plane power distribution.
