I already had someone help me answer if I can crossfire two cards in my build, I'm just troubled on if two different sapphire cards will work together.

This is the version I have:

This is the card I'm having trouble seeing if I can crossfire with:

I'm unsure if they will work correctly together. I do know that they need to be the same brand, but I don't know if they have to be the exact model too.
Thank you for all of your answers.

Yes they will work together and if the clocks are different then they will both work at the lower of the two.

The general consensus has always been matched Vram size. If they both have, say 1 gig Vram, the Mboard can run the two cards at the lowest memory and gpu frequencies of either card. If you own both, you will hurt nothing by trying. If you dont, wait for a close match.
Cards of different vram size will not pair in xfire or sli. (I think)

Could you explain what you mean by clocks?

Hi - Yes they will CF. You need to insure your mobo supports CF and you have sufficient PSU power
along with the 4 pcie connectors (each 7870 requires 2)

The clock speed of the GPU. One is clocked at 1050mhz and the other is at 1075mhz so they will both run at 1050mhz.
