Please help me choose my GPU

Hi, I am thinking of buying either HD 6870,GTX 560 or GTX 650 ti...
Which is better considering I will be playing latest games such as AC-III,crysis 3 etc??

Budget?

I dont understand,these three cards are my options

Ok, as you wish - definitely the GTX 650 TI
it considerably faster the 6870:

and equal or faster than the gtx 560, but much more energy efficient

Or a step up for the 2gb version :http://www.newegg.com/Product/Product.aspx?Item=N82E16814131473 175$ after rebate
or if that doesn't suit you
1gb version http://www.newegg.com/Product/Product.aspx?Item=N82E16814150642 160$

I believe both of these cards should handle most modern games on high or ultra

comparasion of 650 and 7850 http://www.hwcompare.com/13466/geforce-gtx-650-vs-radeon-hd-7850/

Good Luck

If none suits you then out of the three I would pick the 650ti, it's effcient fast and fairly good and on newegg you get ac3 for free with it. It costs 160-180. 7850 is a lot more powerful though and costs about the same, with it you could probably play crysis 3 on high. and crysis 2 on max but 650ti is unlikely to play many games on max well.

Best are probably an xfx radeon hd 7079 which I found at the price of 300€ on alternate.de otherwise maybe a nvidia gtx 680; the nvidia stuff costs a bit more than amd I find, however the software on amd components is shite.
