I just recently bought a gtx 470, to replace my current 8800 ultra card, i was wondering if any of you knew or had much experience with using a 2nd card for physics and if the extra heat generated and power consumption would be worth running the 8800 as a physics card.
Both have water blocks so the extra heat from the 8800 would get tossed into the loop, which consists of a 3 fan 140mm and a 2 fan 120mm rad. so heat should still be ok.
As far as the games i play, i play a good variety, SC, GTA, WOW, Metro, Crysis, Ect. And if anyone knows what kind of fps boost would i even expect in games that used physics engine

It's not really worth the extra power consumption, IMO. Add in the fact that you're adding extra heat into your loop should be the deal breaker.
I threw my 8800GTX on with my GTX295, and saw a frame or two. Negligible.
@ mal: my psu can supply the power, its not a concern. The only question i have is whether the card would give a decent performance boost or if it would be better to just leave it off.
