New GPU Help?

[SolaceGFX]

I am looking to buy a new video card for my desktop. I have an AMD A6-3620 (2.2 GHz), 8 GB RAM, 1000 TB HDD. I know a few things about GPU's but not enough to set my heart on something and drop 100-150$ on something that may not be what i need. I am currently a graphics designer, I use Photoshop and Cinema 4D which currently run with no problems at all. I was really looking into PC gaming but Battlefield 3 doesnt run smooth enough for my liking. All i want to upgrade is my GPU in the price range of 100-150$. I will post a few links to Newegg products I was really interested in. I know my computer isn't the most ideal for gaming but Battlefield 3 is close to running with full frames on medium settings with all stock parts. If you have any recommendations they would be highly appreciated.

I believe the best one out of the bunch you are considering is the 560se. a 560ti is better and i would try to find a cheap 560ti if i were you. As you already mentioned you are aware the rest of your computer will bottleneck the card preventing it from reaching its full potential so i would suggest switching out the a6 for a phenom (cheap) or a cheap amd 32nm
