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?

Technically same card so I would say yes, why not.

Those cards are not made to crossfire with one another.

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

So it will work? People are saying it won't. What do you think?

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. :)
