I'm not totally against the idea of just using 1 card (the 470). I would just feel bad if there was additional performance to be gained out of my 260 that was going to waste.
Oh, actually... now with that option added right into WoW's video settings you can use whatever software you'd like to do it.
I apologize I am still adjusting to Cataclysm as I'm sure most people are.

I'm not 100% sure you would gain performance, if you've got the cards you might as well run some tests yourself. I would say
the 470 should be sufficient to run 5 games on, let alone 2.
