HD6770 + HD6850 possible?

Garrgoyle · Mar 10, 2012, 08:13 AM

Hello. I know you can crossfire two ati cards from same core family. Is this combination possible (6770+6850) and what kind of performance gain can I expect?

de.das.dude · Mar 10, 2012, 08:21 AM

no. they are not the same. 6770 is the 5770 where as 6850 is barts. so definitely not

no you can't, you can crossfire different branded of the same model but not different models.

I dont think so mate unless somebody here knows a hack. If youve got the two cards, try it and see what happens.

No!
Only the same series like 6850/6870 or 6950/6970 or 6750/6770 etc..

Yes, you can. All you'll need is this motherboard.

But instead of doing that, you could;

a. Sell 6770 spend a little more and buy a 6850.
b. Sell 6850 save a little and buy a 6770.
c. Sell both and get something else
