Asus P4C800-E deluxe
Abit IC7 - Max3
GIGABYTE 8KNXP (REV 2.0)
I had a similar choice a while ago, and the reviews say they're all great boards, which doesn't help when deciding between them.
Most people tend to favour the Asus as its capable of very high fsb, but you don't overclock, so thats irrelevant, but I've heard of all of those boards doing 280+ fsb anyway.
Abit make great boards, usually very solid.
Personally I got a DFi Lanparty pro875B because I couldn't decide between the abit/asus, and the Lanparty was actually cheaper ........ with lots of goodies, and cmos reload is a really nice touch.
Oh and my pro875B with an overclocked Prescott (2.8 @ 3.5Ghz 250fsb) hasn't been switched off since I installed my new hard drive about 2 weeks ago, house hasn't burned down yet
Sorry if that doesn't help much, but I think you should consider the DFi as well
