Your board is fine mate.
My main reservation is with it being an matx that those gpu's are going to be incredibly close together.
The wrong model cards are going to run hot mate, & your case cooling needs to be properly up to scratch,& also your PCI express 1 & 2 slots will be completely unuseable with 2 cards installed.
I'm assuming you already own 1 card & are looking at a cheap upgrade adding another used one ??
If you don't own one already I'd honestly look at a single more powerful card personally.

Mate - for some reason I read 7950's !! :-/
A pair of 7850's - you'll get away with a good quality 550w PSU easily.
King of changes things a bit now - the 7850's don't run particularly hot at all , you can also crossfire with the r7 265 - for a $100 or so upgrade it aont a bad choice.
On titles that fully support it you're looking at close to 390/gtx 970 levels of pure performance discounting the lack of vram.

hey mate thanks for the advice so far I picked up a better psu recently so I ended up giving Xfire a whirl, I'm getting some good results (after a bit of tinkering). Im running 2x 7850s but the gpu clock and memory clock speeds are different. 950/1250MHz vs 840/1200Mhz, does that matter should I lower one to match the other?

Doesn't matter mate nie , the last 5 or 6 driver revisions allow independent clock speeds.
Used to run at whatever clock speed was in the slot 1 card so unless you have a good overclocker in the slower card it needed to go in slot 1 & down clock the faster card.
You're all good.
