They made the 275 with the 250 for pysics because the GPU has a hard time doing both and cannot at the same time and I quote(or paste in this case)

Optimizing PhysX performance
PhysX can run on the same GPU that's performing rendering, but the performance will be sub-optimal. This is because the GPU can't run PhysX and render your graphics at the same time: when PhysX calculations need to be performed, a "context switch" from rendering to CUDA must occur, and another context switch is required when switching back to rendering. Although these context switches occur very quickly (on the order of microseconds), they also must occur very frequently, and the context switching time extracts a noticeable performance penalty (one of the performance advantages of NVIDIA's forthcoming "Fermi" architecture is that context switching is much faster). Context switches take so much time that PhysX running on a relatively low-end GPU that's dedicated to the task will handily outperform PhysX running on a high-end GPU that's also performing rendering.

I will be installing the 8800GTX just for physx and will let u know how it goes.

WWhat E88 said (did not know that before ) and the 470 is fast, but it's not THAT fast.

Well I guess a dedicated physx card will help it out, but as the 470/480 have greater compute capabilities, I'd imagine they could still hold their own alone (not got any Physx games installed atm).

I sold my 8800s before I got chance to test it myself :P

I don't really know how many games support Physx, but is not it dying out a little?

8.17.11.9741 driver!

Since installing the new card the only thing I noticed is longer times to enter a game and update stats in BC2. Kinda wierd.

Huh? Bad Company 2 Supports it.

Oh ya and I wanted to add that 100% fan on sounds like a jet aircraft! But keeps it cool really well. 85% keeps the card cool and the sound is not rediculous.

Not sure if BC2 supports it or not. I do not show any GPU usage from my 8800 while playing????

Nope, it doesn't.

And the reason why you are loading slower is DX11. It's a bug that should be fixed in drivers soon...hopefully.

Defenitly good to know, thanks. I think I have figured out why I'm only getting in the thirtys for FPS with my new card. Having the 8800 in the other slot splits the bus so each card is defaulted to 8x instead of 16????? Sound right?
