Crossfire 5870 question.

post #1 of 4
Thread Starter 
I currently have a stock Sapphire HD 5870 and I'm looking at getting another used 5870. Currently I am eyeing a XFX 5870 that says that it is factory overclocked and the XXX edition. (they are both 1gig). My question is, will there be a problem using an overclocked with a stock. If not, would you recommend using the OC as the primary? Thank you for your time.

Those will be completely fine. The overclocked version would be best as the the display.

5870 Crossfire is real powerful.

I am also looking into getting another 5870 to run in xfire and though I would just ask here instead of making a whole new thread.

How well do these cards scale xfire vs single, and does it differ a lot game to game? If they don't scale all that well maybe I am better off getting a new card.

They can run at their own respective core/memory clock and voltages fine, even 4 AMD cards can do just fine. It doesn't matter which one is set as primary, just select the card with better heat dissipation on top as they are normally run hotter due to air flow restriction of the second card. Crossfire 5870s are amazing in scaling for one screen upto 2560 x 1600.
