I have an HIS 5770 1gb model that i bought about a year ago... im looking at selling it and upgrading to a 6870 or 6950. Ive also thought about crossfire. Im not a big gamer but i feel like upgrading. My monitor resolution is 1920x1080 and im running a amd athlon ii x4 645 @3.5ghz and have a 550w ocz fatal1ty psu. I play all call of duty's bulletstorm, and might eventually try bf3 but i havent liked the last few games.
I dont really want to spend more than 200 on a new card but can if needed like for a 6950
Any input would be much apperciated.
My self I like Nvidia. So my answer of course would be the 560. In some benchmarks the 6950 shows it to be a little bit faster and in other one's I've seen the 560's faster. It just depends on you and your prefrence. Here is a link 560 vs 6950.
