I'm really in need of a new graphics card but recently it seems like there's been a flurry of activity. I'm looking to play current gen games on high graphics comfortably without breaking the budget. Recently I've been looking at the R9 270X, GTX 660Ti, GTX 660, GTX 760, and Radeon 7950. Is there any distinct advantage to any of these? Does anybody have a link to a reliable bench between these?
Edit: My current rig is as follows
AMD Phenom II X4 965 BE
G.Skill Ripjaws Series 2x8gb
Nvidia GeForce 9800 GT
Cooler Master 600w Power Supply
Samsung 840 128gb SSD
Gigabyte GA-970A-UD3
