newegg is a good place to start. they have a lot of reviews.
they tend to be more on the 5/5 of Asus and some sapphire boards, also on the more expensive side if your budget. I own a gigabyte, and i can tell you know, if you have no plans to overclock, my board does perfectly. Abit, another good company in this area, makes boards similar to gigabyte, but with a bit more "freedom" per say.
DO NOT BUY PCchips. horrible mobo's, ick. and MSI is eh, but your saying nay on that, so no further comment. I really haven't heard too much on DFI
again, as i wait for them, CTJoyce and Nick N are the Chief Chief experts here (im just a chief expert

)
