Yeah, the bridge seems good, and you don't have to spend more on a motherboard, where you might not use the AGP function for more than a few months and then change your card.
That Abit board should be good. I have an Abit, and I'm very happy with it. Mine even came with a UGuru clock, which makes overclocking, seeing fan speeds and looking at temperatures so easy!
Many more companies have the UGuru clock now, but I just liked the way it worked when I got it.
