I found a mobo which might just be the one!http://www.ebuyer.com/349910-gigabyte-ga-970a-ds3-socket-am3-7-1-channel-audio-atx-motherboard-ga-970a-ds3
It has 2 PCI-Express x16 slot's - just incase you want to use SLI or CrossFire.
It can support upto 32GB of memory and 1866Mhz , you can always change this in the bios btw. It also supports AM3 or AM3+ processor's.
I'm more of an Intel man but AMD processor's are still good for some builds!
