GTX 570 + GT640 as physx card

[bliz]

Hey guys,i'm thinking about installing a physx card in my computer, i have a few questions :

1. Is the 640 good for a 570

2. I will only get more FPS in games like batman, unreal engine games and games that use physx right?

3. will the load of the physics card be as much as the rendering card,or it will just heat a bit and be quite quiet? I mean,the card will probably work just a bit for physx right?

thannnks!

If you already have the 640 or similar card then sure give it a try; I'm sure it would work. But if you are looking to buy the 640 new that's around 90 bucks. I would say it would be better to sell the 570 and put down some more cash to get a 670. That's just my 2cents.

Already got a 640 :P my mother is not gonna use it because it's too noisy( my mother wants a PC as noisy as a laptop lol ),so i kindly offered to borrow it^^
