what are you requirements?
If you want to overclock then the MSI isn't great & the abit is good but not great. There is a new version out called the AB9 QuadGT which Gary Key @ Anandtech says is the fastest 965 mobo so far & iirc it's $185 at ewiz & $220 at newegg.
ds3 or p5b-e. Either one you cant go wrong with. Used both in great numbers and haven't had a problem with either. p5b-e has esata and IEEE 1394a (firewire) btw. never worked with the abit or msi boards so i will reserve judgement on those.
