Video card for my apu

i've had my computer now for a year and im thinking of adding a video card to my system.

i have a  A10-5800k apu on a asus F2a85V-pro motherboard with 16gigs of ram. It runs amazing but i would like in the near future also add more monitors.

what should i get?

There are some cards that you can CF with your apu, but i don´t know exactly which models this are. But some people over here will know.

I would personaly just trow in a dedicated gpu. and use that to run  the games.

Budget?

6 series cards can id: 6750 but I don't think that would run 3 screens on anything but 720p in medium settings so I wouldn't recommended it. What's your budget?

ive been looking online again today, and i noticed that amd doesn't really have any 6000 series around and the stores aren't sell them anymore. but now they have a new line of cards like the g7 260x that supports eyefinity. is that maybe what i should be going for?

my budget is anything up to $200 

there might be 7950s diping into that price range, otherwise there are amazing deals on 7870s right now

This is a good 7950 in the $200 range http://pcpartpicker.com/part/his-video-card-h795qc3g2m 

what about using a new amd R7 card? would that be compatible with an APU?
