So i have a GTX 295 right now, im looking into buying a GTX 570, could you SLI those two together?
No, they have to be the same model.
no, you can only sli 2 of the same gpu, IE: 2 570's, 2 295's. however they dont need to be the same vendor, so you can have an asus gtx570 and a gigabyte gtx570. you cant have a 295 and a 570.
Alright thanks for clearing that up for me
You technically can, but with two different cards the lower end one is going to give 0% performance improvement, so there is no point, all it is going to do is make bad airflow

What? No, with two different cards it won't give you the option to utilize SLI. It will let you choose if you want to use one of the cards to calculate PhysX but that isn't SLI.

That's sort of what i meant, must've structured it badly i guess
Can't you set any card that is physX enabled as a physX slave? So don't throw out your old card if you play a lot of games with PhysX, I guess.

Pretty much this.
But make sure your PSU can handle it first. A GPU on PhysX duty takes up about 200 something Watt.

Would say, a GTX285 for PhysX use as much energy as a GT430 for instance?

Nope.
TDP for 430 is about 50 watt and as far as I know it wont give you as satisfactory performance as the 285.
I heard a lot of good word about the 285 in dedicated PhysX
this info is worthless here probably but ATI cards dont have to be the same for crossfire.
unless thats been changed since the 4XXX series
