5850 + 5870 crossfire not allowed in the ATI Chart?

I saw the chart posted in the Crossfire sticky here, and it says that a 5850 can't be paired with 5870? I see reviews on the internet where people have done that and have been successful.

I was planning to get a 5870 to pair with my HIS iCooler V 5850, since I always play at 1900 by whatever resolution and I think it'd be a good upgrade instead of adding another 5850.

Can someone confirm if this is a mistake in that chart, or for some reason this is not a recommended pairing even if it is possible?

Thanks.

first of all yeah a 5870 and 5850 will crossfire just fine, but you will best suited with a second 5850, from my expiriences with 6870 crossfire I would advise against it bc of poor crossfire drivers and hassles, low minimum fps, its not worth the hassle imo, if I were you id sell the 5850 and get a 6970 or gtx 570

Selling 5850 is a losing a lot of money unnecessarily. That card was close to 280 when I got it last year, and today it won't go for more than 125 dollars. Adding another used 5850 at around 125 dollars is in my opinion a better idea.

But surprisingly, brand new 5870 is available at the same price as brand new 5850 these days, and 5870 is at least 15% better than 5850 so I am not sure how 5870 + 5850 would yield slower results than if I were to match two 5850s. What took me by surprise was that the ATI official chart does not show compatibility even if they are both from the same family.

I'm pretty sure they can work, but it's not recommended. The performance would not be better than two 5850s, because the two graphics cards have to output at identical rates (they crunch the same data) so the 5870 would be slowed down to 5850 speeds.
