Which is faster, 2 Radeon HD 6770's in crossfire, or 1 Radeon HD 6870

I'm not concerned about the space or heat constraints of a crossfire, as I have a large case with very good cooling.
So this is just a question about which would be faster in gaming at 1920x1080



Rest of system specs

Core i7 920 (oc to 4.0ghz)
6GB tripple channel RAM
2x 750 GB WD Caviar Blacks (raid 0)

simple answer; a 6870 or better yet a single gtx 560ti. From my experiences xfire works like crapgo for the best single gpu u can afford

CrossFire performance has improved significantly overtime, but it still needs further improvement IMO.

Here is a Radeon HD 6770 Crossfire review over at Guru3d:

It looks like that crossfire option is superior to the single card option.

Thanks archean. I googled around for a while and couldn't find anything as comprehensive as the article you linked, it was really helpful. From what the article states, two 6770's crossfired is equivalent to a 6970, which answers my question :-)

ha ha yeah right hardly not to mention the inherent problem of low end crossfire, crippling minimum fps and terrible drivers, Id go for the single card. crossfire 6770s is on par with a 5870.

Have you ever actually run crossfire, the drivers are terrible and the issues that the OP will deal with do not justify the performance, not to mention that minimum fps will be piss poor, the OP is better off going with a single 6950 or gtx 560ti imo
