Also when there's a lot of tessellation, the 7970 will blow the 2x5850's away, because the 5xxx-series is very weak on that front, even w/2 of them.
If I had a 5850 I would prefer to sell it and get a 7970 (or a 7950, those will likely be a lot better bang-for-buck cards) rather than going 2 x 5850 ... however, if you're already nicely set up for xfire (i.e. a board with the support and a 700W PSU or better), I don't think there's any question that value-wise, grabbing another 5850 is going to be a lot cheaper path to pretty similar performance.

Agreed, I'm going this route. Just bought another 5870 for x-fire should be similar performance for a fraction of the cost. Little worried about x-fire related issues, but that's part of the fun of being an enthusiast. Enjoy! BTW you can probably pick up a 5850 for $120. thumb.gif
