Help for new GPU

[ProAsian]

Thanks for looking at the topic. Anyways, I have an AMD APU (A6). It has 3650 integrated graphics but I need something more. For example, Battlefield 3, on low, is pretty laggy. My budget is about $200. A little over is okay. Anyways, please give me some suggestions on which graphics card I should get. By the way, I have a 550 watt PSU. And I'm pretty sure that in this price range it doesn't make a difference but, I only have 1 pcie slot. I want to try to future proof as much as possible despite my budget. Thanks for the help in advance.

your amd APU(A6) would bottleneck practically any gaming graphics card.
I would recommend nothing over a hd7770 ghz edition.

there would still be bottlenecks but it should give you a huge performance boost over the hd3650
