Is It Possible To Crossfire My Radeon HD 7870 with an Radeon R9 270x?

Hi,
I have a Sapphire Radeon HD 7870 GHz Edition. I watched this video about AMD Crossfire and I wanted to see if I am right about this. Based off what I heard from I heard this video http://www.youtube.com/watch?v=pGN1na3F5do , Is is true that I can crossfire my Radeon HD 7870 with a Radeon R9 270x? If so, how much of a performance increase would I get?

  1. Technically same card so I would say yes, why not.
  2. Those cards are not made to crossfire with one another.
  3. 270x has the memory more faster than the 7870. you can get a bios from 270x model. but u need slowdown the memo. because you will kill your card if you try get it inside. My 260x gigabyte is rebranded model 7790. 1gb it have only a stick "260x"

    Why? Did you watch the video? Sounds like it would work. Can you give me more detail on why it would not?

    Sorry what did you just say? I didn't understand any of it. I'm kind of new to PC building and Crossfire

    Completely unsupported statement.

    They are essentially the same card. Furthermore, Crossfire plays nicely with other-spec cards within the same architecture, so as long as you are crossfiring Tahiti with Tahiti, Pitcairn with Pitcairn, Barts with Barts, etc, then you are just fine.

    I am currently crossfiring a Gigabyte 7870 OC Windforce with an MSI R9 270x Gaming, and they working brilliantly together. Heaven benchmark (1920x1080, max settings) of 1305 (51.7 FPS)

    Correction: Score of 1375 @ 54.6 FPS. Helps to unplug your second monitor, even if you are only running the benchmark on one screen. :)
