What is your price range ? 100 to 250 dollars ?
You want a micro board or regular sized. ?
How much RAM do you intend to use ?
I would make sure if they are shipping with the newest bios, since I believe you need a bios update to be able to use a vishera chipYou want a 9x0 board IMO.
The 970 is the cheaper chipset vs the 990's.
Here is a 970 for $60 AR

As long as you get a 970, 990x, or 990fx based board you should be fine.
