I haven't necessarily heard bad
things about Gigabyte if that helps. As I've not owned a Gigabyte motherboard I can't give a really fair evaluation. I did, however, own a Gigabyte Radeon 8500. It was good quality hardware, just the drivers didn't work like my GeForce3 did.
As long as the board is functional and stable for you with the hardware you have in it, that's all that matters.
