Adding a HD 3870 to my HD 2900xt 1GB

[Wog2000]

I am thinking of adding an HD 3870 to my puter in crossfire. Will this cause any problems? My concern is the 3870 has 10.1 and my 2900 is 10.0.

Wha? No the 2 cards need to be the same

uhhh...they have to be the same card for crossfire haha

OK, Thanks.

no they don't....

for Crossfire they can be any two cards..

ya but the 3870 uses the new gen crossfire, but the 2900 only uses the external dongle.

thats true... but I'm just talking about the people who said it has to be the same card, I think it can be any cards in the same series

ya it can be any card, but both cards will only run as fast as the slower card.

Can a corsair 520 hx PSU crossfire 3870's? Or is that too much for the PSU

yes it can... lemme guess planning on changing your build again

a Corsair 520hx is the same thing as a Corsair 620hx (the extra 100watts come from the 3.3V Rails) it can power 2 Ultra's with a heavy oc'ed quad-core
