This is what I'm getting after I overclocked them and turned the fan up a bit.

But HELP!! Should I disable or enable crossfire?

Should I take the crossfire bridge off physically too?

I am using these drivers:

the latest BETA 13.3 ones.

My setup is also in crossfire, does this hinder my performance?

i was able to get 650 Mhash from both of my cards clocked at 1100 Core clock, but i did have to run the fans at 70% 24\7 so if noise is an issue just keep your cards at 925 clock and accept the 1100mhash instead of 1300. or find a comfortable middle ground you are comfortable with.

Okay, which number is the correct one?

Is GPU 0 my first 7970, and GPU 1 is my second 7970?
Probably Yes. You know, computers like to start counting from zero, so 0 is first card and 1 is second card. If You are confused about two speed indications for each card then know that one is current speed and another is average speed over time.

What are you using for drivers (amd cat and APP)?

You should be able to get a bit more from those cards.

They mean speed. If not satisfied try to test various settings in mining software and then overclock the cards. Watch for temperature and stability.
