My first question is how many did you start with lol
....that is about all of the PE mobos, anyways
Out of the ones you have chosen I will give you the good and bad of each and then my recommendation and you can decide...
They all of course are going to perform about the same since they are all based on the same platform and chipset. It is the features and quality that sells
First of all here is a great review on all of these motherboards....
<A HREF="http://www.anandtech.com/mb/showdoc.html?i=1723&p=1" target="_new">Msi & Gigabyte & Asus</A>
<A HREF="http://www.anandtech.com/mb/showdoc.html?i=1771" target="_new">Abit</A>
After reading these reviews you will notice that the Asus is prob one of the best performers although the margin is very slim...the asus prob falls in the middle of overclocking performance...you will notice that the Albatron is the best overclocker which also makes a kick ass motherboard that you didnt list, along with Abit. The albatron they reviewed was the slimmed down version and they have a better one out called the ProIIS which is available at newegg and offers sata raid etc...The bright spot on Abit is that it offers dual channel ide raid which none of the other motherboards do. If you are planning to run ide raid I would look no further.
You will see that the msi is a mediocre performer overall, and the gigabyte is a good performer and has good features all for one sour spot. It doesnt offer many memory divider options. DDR 400 will be very hard to reach on this motherboard so if you are a memory overclocker I dont suggest this mobo.
<font color=red>My recommendation is the Abit-IT7Max2 rev2</font color=red>
Or you can wait on the sis655 motherboards which will support dual ddr400
