i've heard that crossfiring can reduce performance drastically, so i'm wondering how to use both cards independently

What software do you use to mine right now?
What's the hardware setup?

I was in the same boat a few weeks ago.  All you have to do is plug the cards in, that's it.  No need to Crossfire.  Depending on your driver version, you might have to use a dummy plug in one of the DVI ports on the card(s) that aren't hooked up to real monitors though.

GUIMiner will ignore crossfire settings (at least that has been my experience).  Regardless if crossfire is enabled or not GUIMiner always displays the GPUs independently.
