Summary: I bought 2 of these cards upgrading from 2 GTX 470's. Some games such as Borderlands do not like SLI on these dual cards. Otherwise fantastic on all games after got the bugs worked out and SLI turned off.
Summary: I am using this video card for about 10 days now, running BF3 on max settings, tested with Crysis DX11 + HD Texture pack and Skyrim with HD texture pack. I can say that the card is good, handles these games on maximum settings but it's not better than my Radeon 7970, I think it's the same level.
