I like models on Tom's list at http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html
There is no issue of bottlenecking for a single GPU (or even a double on one card) with that CPU.
You did leave off the case size so you have to deal with the mechanics.
I recently bought a new computer but fell short of cash when it came to buying the graphics card, ive built the rest but know litrally nothing when it comes to graphics cards.
now obviously I would like to get one that's 'in line' with the rest of the computer, ie. not have an amazing one in a bad computer/not have a bad one in an amazing computer.
the rest of the parts are as follows:
1TB Seagate barracuda 7200rpmsata3 64mb harddrive
asus m5a78l-m/usb3 am3+, ddr3, gblan, 7.1snd, matx
amd fx-8350, 4.0ghz, 8-core, visgera, 125w,am3+ cpu
hyperx fury (2x4gb) ddr3 1866mhz (will be upgrading to 4x4gb)
corsair cs series 650w modular 80plus gold atx psu
I didn't know what would be needed so I just copied what was on the invoice word for word
thanks in advanced for the help
