non overclocked, 320-340 kh. I play games as well on my machine so i would need crossfire.

Same. I have crossfired 7850's. If I leave the bridge off, my system is really unstable. If you use the system as your desktop, I'd recommend keeping the bridge on or using the 7950.
With the bridge on with my AFK setting, I get 350 KH/s per card, 700 KH/s total. While I'm using the PC, I get 280 each, 560 total.
A 7950 will get you ~600-650 dedicated. I'd go with the pair of 7850's regardless. (several 7950's are better than several 7850's, obviously. But 2 7850's is better than 1 7950)

Do you get 560 kh whilst gaming or just using your pc?

No, I turn off mining while gaming. You could keep it on with -I d and get maybe 50 kh, but I wouldn't recommend it.
560 kh/s watching videos, browsing, posting here ;P , etc. Pretty much anything except gaming. At -I 12.
AFK is -I 16 (what I use anyway)

crossfire slows your mining if you are gonna use 7850x2 then let it be without xfire. whats your current hash rate? two 7850 if tuned proper can give you 750~800kh
