There are a lot of other features that differ on each mobo, there are no two exactly alike. 890 is the latest chipset but that doesn't mean 785, 790, even 770 are bad. State your CPU and budget and we can pint you to some good mobos. Also if you intend to crossfire.
thanks,so what is your suggestion ? i want to buy an amd phenom ii x6 1090t.
Gigabyte GA-890XA-UD3 is a nice board. A cheaper one is GA-770T-USB3 (no crossfire).
