Default Adding a HD 3870 to my HD 2900xt 1GB

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.

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

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
