I currently own an Asus A7V400-MX SE, but my friend is giving me a Gigabyte GA-7VAXP. after comparing the 2 I cannot decide which is better. I do not use the integrated gfx on my asus, so its a waste of my memory, and the Gigabyte supports 3 ram slots. the asus supports DDR 400 ram, but it will only run at 333 MHz so it doesnt matter. Both have VIA chipsets. the asus is micro atx and the gigabyte is atx. here are some links:
