Looking for a video card

You're asking the wrong question in my opinion. I have no idea what you plan to use this videocard for, so how could I recommend something? Your APU can run some less demanding game very well, but you won't need the fastest card for those games. Your APU will struggle on demanding games, the fastest videocard won't change that.

So it depends on what you plan to do. Plus we haven't even brought your power supply into the discussion, that right there may limit your choices all by itself.
