Can my PSU Handle it?

I'm intending to hook up two GTX 570 2.5GB versions, an 8800GTX and a 2600k. I have a Corsair 850 HX psu, can it handle it or do I need a new one?

It will be fine.

Whats the 8800GTX for? PhysX?

Which NVIDIA GeForce GPUs support PhysX?
The minimum requirement to support GPU-accelerated PhysX is a GeForce 8-series or later GPU with a minimum of 32 cores and a minimum of 256MB dedicated graphics memory. However, each PhysX application has its own GPU and memory recommendations. In general, 512MB of graphics memory is recommended unless you have a GPU that is dedicated to PhysX.

You might find that using a slow card (these days) as a dedicated PhysX card will be slower than just the two GTX570's.

I seen a video that showed a GTX460 sort of card was best.
