Personally, motherboard PERFORMANCE is not a big deal to me. Although sites have benchmarked mobos, I believe you can't even tell the difference in "real world applications", or games.
Therefore, I would probably look at the functions of each board, and pick one that will do you the most good.
On that note, I got myself the Soyo Dragon+ cuz it just ownz in the amount of features that come with the board. Check it out. 🙂
