Sorry for the noob question..
This is my build. Can I cross fire the saphire 7850 with any other 7850 gpu? Or does the graphics card have to be exactly the same?
For example can I use a vision tek 7850 like this one http://www.amazon.com/gp/product/B007KJ1URG/ref=ox_sc_act_title_1?t=slicinc-20&tag=slicinc-20&ie=UTF8&smid=ATVPDKIKX0DER

Thanks! :)

  1. it can be any. you can even with a 7870 I'm pretty sure. nice build though
  2. great thanks!
    Is there a way to know which gpu's I'll be able to crossfire together and which ones I won't?
  3. Best answer
    In general the can be crossfired if the first two numbers are in the same. You'd never want to do a 7870 and 7850 though as the stronger card would be crippled to match the lower.card, and it's be a waste of money. Therefore it's usually better of they match exactly. It's just a nice option in case you can't find a perfect match later.
