4870 + 3870(s)

post #1 of 5
Thread Starter 
I'm thinking about buying a 4870, but i dont want to give up my 3870s yet. Does anyone have or know where to find benchmarks with the mixed CrossFireX or have any thoughts on the setup?

As of now, mixing the 2 series does not work.

I don't think you can. It was verified with ATI people.

ATI official

Despite previous reports on the internet that old Radeon 38x0 and new Radeon 48x0 cards will work in Crossfire together, unfortunately this won't happen.

Two senior software guys at ATI has (you mean have) just confirmed that 3800 series in Crossfire with 4800 won't work and that such configuration is not supported.

You won't be able to miss (you mean mix) and match the generations and we are investigating if you should be able to mix the cards from 48x0 series. We believe you should but we won’t jump gun with this announcement.

Sorry for destroying one cool dream but you will have to sell or throw your 38x0 card and swap it for much faster 48x0 generation.

At the same time our friend W1zzard from tech power up has confirmed that he didn't make 3800 and 4800 generation to (scratch the to, not needed) work in XP but now we know the answer why. It won't work on XP or Vista simply as its not supported.
Sorry mate
