Searching for a video card

Hello steamgifters! I have been surviving with an integrated video card until now, but I think it is time for something better, and I thought you could help me choosing, because you are kind and helpful :)

• Processor: AMD A8 5600k 3.6GHz (APU HD7560D 512MB) (trinity 100W)
• Motherboard: Asrock FM2A75 PRO4-M (PCI Express 2.0)
• Memory: G-Skill 4GBx2 DDR3 1066MHz
• Power source: Seasonic S12II bronze 520W

I am limited by my power source and my processor. My budget is around $200/200€. My monitor is 1920x1080 and I would like to play games like GTAV, Sleeping Dogs, modded Skyrim (those HD texture packs eat a lot of graphics memory)... with good graphics and a decent framerate (60 :D).

Thanks^^

EDIT: Are you trying to match the poll on purpose? :S
