I've read reviews and benchmarks for both cards and I know the 6870 is only slightly better but I'm still not quite sure which will be the best. My resolution is 1920x1080. My tech level is quite low so I probably won't overclock and I would like to know what your opinions are. My budget is $200 if you have other cards you would like to recommend.
Games I would like to play: Shogun 2, Diablo III, Skyrim, BF3.
Of course, if you have any other suggestions I'd be happy to get them. Thank you in advance!
I have a 6870, and it's very good in Skyrim & BF3. I can run on high settings @1080p, and ultra on lower resolutions. I had the same problem you do, but I went for the 6870 and I don't regret it. If your budget can spare it however, a 6950 or better would be ideal for Ultra on BF3 @1080p.
