I got the 650 ti to use as my main card, and now I have my 550ti just hanging out in my closet. Would the 550ti take the load off of my 650ti and help out my games as a dedicated Physx processor, or would it be better to just leave it uninstalled? My mobo has 2 extra PCI-E slots that aren't being used....

My major components:
Board: Intel DX48BT2 (pretty good OC board, by the way :D)
CPU: E8500 running at 4.2 Ghz
PSU: Thermaltake ToughPower 750w
Installed Video Card: Gigabyte GTX 650ti OC Edition 1GB

Spare video card: EVGA GTX 550ti (Best Buy Exclusive OC Edition) 2GB

I think I read somewhere that nvidia no longer supports using a dedicated physx card. But if they still do I don't see why it wouldn't work. Also even if it is possible drivers might not be all that great and give you worse performance. I guess it can't hurt to play around a little though.

According to my Nvidia control panel, I still have the option....Maybe they took it out with the new drivers (320), but the new drivers are crap and wouldn't work right....I'm on the 314.22 version which still gives me the option....I just can't seem to find any infor anywhere regarding using these 2 cards together....

The GTX 550 Ti would pair very nicely with a GTX 650 Ti as a dedicated PhysX card. And of course, Nvidia drivers allow a dedicated PhysX card to be run in the same system, always have. You should see a nice boost in GPU-accelerated PhysX games, but only in those games, otherwise the additional card will be useless.

So the big question is, what GPU-accelerated PhysX games do you intend to play?

I just got it hooked up, and it makes a rather large difference, as far as PhysX effects are concerned....In the benchmark for Arkham City (on the maxed settings), my minimum frames don't drop below 30fps, and average about 57fps....I'm well aware of the fact that for the most part, having a dedicated PhysX processor doesn't matter....I'm big on only posting after I realize that my answer isn't currently available anywhere....I play games like:
-Arkham Asylum
-Arkham City
-Borderlands 2
-Metro Last Light (I'll start playing it eventually, :) )
-Warframe (occasionally)

I'm not sure where you're getting your information from, but the 650ti handles graphics quite well on it's own....I just wanted to be able to enable that option on Arkham City that basically requires you to have a dedicated PhysX processor....You shouldn't believe everything you read, that's a very bad habit.... ;)
