I will be getting 2133 memory or better for sure. The cheapest 2133 or better on newegg right now is 2400, F3-2400C11D-8GAB. Just need to pick a MB. Anything I should look for when getting a MB for an APU. New FM2+ boards seem to start at $40, but I don't really know anything about AMD's chipsets.
This one, http://www.newegg.com/Product/Product.aspx?Item=N82E16813128694, is $35 after rebate.
