How much better scaling is 6800 over 5800 amd cards?

I have a 5850 already and was planning on xfireing another card. Newegg has the card for 170 right now.

Now with the advent of the 6950s awesome scaling, I'm curious what the difference is between the scaling %.

How much better is the 6950xfire over the 6850xfire over the 5850 xfires?

I'm running 2500x1600 and i'm wondering if it makes sense to just sell the 5850 and get the better cards.

Also, I guess I have to keep in mind that getting new cards will be vastly more expensive than getting another 5850 for 170 after rebates?

What's the right move here?

Not much
"We explicitly talked to AMD about CrossFire scaling after its press briefing. According to the company, it didn’t make any changes to the Radeon HD 6800 series that would have improved its CrossFire scaling versus the Radeon HD 5870, as many folks suggested in our 6800-series launch coverage. It did, however, incorporate driver-based enhancements that augment CrossFire performance in the 6900 series. This seems to be reflected in the results here.

Now AMD says that the 6800s will get the CrossFire-oriented improvements in a future driver update. For now, though, 5800-series and 6800-series cards should scale comparably, with the 6900s doing even better."
So thing will get better for HD 58xx series with future drivers

Ahh...just finished the article. Good to know.

I see that some scaling for amd is up to 90% for 69xx. THat's awesome, if the card wasn't such a dud.

Now it makes me wonder if I should buy another 5850 to xfire or just ebay my current card and go for the 570....

Assuming the card sells for 100 bucks, it's a 100 dollar extra to get a 570 over purchasing a 2nd 5850.....what to do what to do....

2 5850s perform better than 1 GTX 570,so you get something faster and cheaper.
