I have a Matrix 7970 card, it works great and Im not ready to purchase a larger card yet, however I would like to get some more fps out of my current games. I found someone with a 7970 card for $90.00, will this card crossfire with mine since there both 7970's or do i have to have another Matrix?

Hello immaturegizzmoe

You can crossfire two 7970's no problem.

+1 Nate. Additionally, and this isn't critical; but, for the sake of performance, it's not a bad idea to make sure the model numbers match too. Those cards should end with a "V278" or something like that.

EDIT: I say that only because some different versions (but, same manufacturer) have clock speed differences - the two cards in X-Fire will run at the lower speeds, unless the lower speed GPU/VRAM is OCed to match the higher one.

Hi guys

Different bios's on the gpu's shouldn't be a problem, my 680's have different bios's and run just fine.

Why should there be any problems with different bios versions? Even with 2 exact same models the chances are slim that the bios versions are identical unless you purchased them at the same time.
As Z said there might be some performance left on the table if you get a second card with lower clocks than the Matrix. Plus on some older games frametimes can be really bad due to missing frame pacing for Crossfire on DX9.
