Will my PSU need to be upgraded to handle 3 cards?

Hi, I plan on upgrading to an SLI setup with the next gen nvidia cards (600 series) and would like to know if my psu will be able to handle it. I'm aware the power specs are not out since the cards are months away. For this reason I'm just going to use the gtx 570's as my reference since thats about the model I would go with (670).

Right now I have a gtx 560ti and would rather it not collect dust in my drawer so I plan on using it as my physx card. Thats why I'm unsure of my PSU's ability to handle 3 cards.

My specs:

PSU - corsair hx1000
CPU - Intel Core i7 930
Graphics - gtx 560ti with 9600gt physx
Drives - wd raptor 300 gb, 3 - 2 tb wd caviar greens
Case - antec 1200

Thanks for any input.

why not just sell the GTX560ti and 9600GT, then pay very little for the GTX570. add a second GTX570 down the line. two 570 in SLI will handle gaming + physx just fine. you can even keep the 9600GT as a physx card (it's not that demanding)
