Using 2 different graphics cards

Question

I have an EVGA 9800GT on my PC and I'm running Arch Linux x64 with 2 monitors. I have a 9500GT sitting in the shelf. I found out that I could use the 9500 for physX, but I can also SLI them. Doing SLI with two different cards has a performance impact , but is this true with these cards which are almost the same?

Also please give me some notes about how to set this up on linux (either SLI or physX thing).

You cannot use graphics cards with different GPUs for SLI.

Can I mix and match graphics cards that have different GPUs?

No. For example, an XXXGT cannot be paired with a XXXGTX in an SLI configuration.

@ChrisN Your answer is only 50% correct in its current context.

Can I mix and match graphics cards that have different GPUs?

AMD(CrossFire): Yes, it's called CrossFireX Hybrid

Nvidia(SLI): No

"I found out that I could use the 9500 for physX.."

True. You can mix and match Nvidia GPU's from the 8800 series and above. One will act as the Graphics processor and the other as the Physics Processor.

Note: ChrisN, if you want to incorporate these facts into your answer, I will delete this one.
