both company make solid cards for AMD but generally most people like XFX because of the customer service (though i'm not sure how is this in your country) and warranty deals. your cpu should be able to handle 6770 or 6790 but you can OC your cpu if you want to eliminate any possible bottleneck. other than that you're good to go

Ok.Thanks a lot. And what difference between 6770 and 6790? Should i go with 6790 when it cost more about 5 % than 6770?

6790 is 256bit and 6770 is 128bit this is diffrence but both are ddr5 and dx11 support that is the new feature of cards

 

[pell380]

another diffrence is 6790 require more watts

I mean what difference between 6790 and 6770 in performance in games? Preferable resolution - 1280x1024.

6790 is a bit faster than 6770.

Ok. Thanks. And what you think about GTX 550 Ti? Same price as 6790.
Update. I see(Link from renz496) that 550 Ti is a bit slower
So best choice is HD 6790? (If i overclock cpu)

 

[renz496]

6790 was released to beat nvidia GTX550 Ti. i think your cpu might bottleneck the card a bit at it's stock clock. but you should be good if you can push your cpu upto 3.4Ghz and above
