Good deal on ATI 5850? Crossfire compatible with mine?

I can get an "ATI Radeon HD 5850 1GB DDR5 Graphics Card With 1080p HD-3D HDMI Port, Display Port & DVI Port + Fan Cooler!" for $120. I already have a Sapphire 5850 that I bought in January of 2010. Can I Crossfire these two even if they are different brands, they seem to have the same specs, I've just never had more than one GPU... I know I don't "need" to do this but I figure if I can get one cheap before they stop making them I'll be set for a few years. Here are my specs:

  1. Yes, that will work fine. Are you using this for gaming, and if so what resolution?
  2. Yes you should be fine. Even though they are from different companies - they are still compatible.

    I believe it is similar with say a 6850+ 5850, but you would need the 6850 as the first GPU, and the 5850 as the second.
  3. 1920 x 1080 for now.
  4. Well, I ordered it...
  5. We have almost identical setups! Yeah it should work no problem.
  6. Oh, BTW... how do I install it? :P

    Simply connect everything and it should be recognized? Maybe mess with a few things in the ATI software?
  7. 1) Shut down your computer

    2) Install 2nd GPU.

    3) Install Xfire bridge.

    4) Turn on computer

    5) You might have to re-install the catalyst control center software, although not 100% sure.
  8. Cool thats what I figured, thanks.
