post #1 of 5
Thread Starter 
ok so i have 1 wc'd xfx 5870 version 2 and am about to buy a asus 5870 reference card "version 1" and wc it and was curious if i'll have any trouble cross-firing them and is it bad to run them at different clocks? any advise is welcome. thanks

I believe it will downclock to match the slower card. But will run fine.

Just make sure the one with higher clocks is in the first slot. But really its not going to make a difference. And you can always OC the cards to match each other as well
