I've been using Gigabyte boards for my builds recently and haven't had any issues. I hadn't heard about abit's departure from the market. The abit board looks to be higher end, with more SATA ports which might be pretty useful, and an extra 16x(4x electrical) PCI-E which is of questionable utility. Both boards have good reviews. I'd call it a toss up because although I'd prefer the higher end board, I don't have any experience with abit... and if they're now no longer in the business you'll probably have trouble getting support if you ever need it. Sorry if that wasn't terribly helpful.
