I know that the APU is FM2. I've been wanting to upgrade my motherboard as well, due to the fact I want more ram and SATA 3, not SATA 2.
It's AMD3+, so I could go with one of 6 different processors with it (only a 95w socket)
Max RAM is 8GB 1600.
I've lost the box for the mobo, soooo, I hope what I provided helps.
EDIT
In addition, will a better clock improve FPS at higher res?
