"PS...I'm also not clear on the issue of running PhysX software on a graphics card without slowing down the graphics performance..."
Many people rate flight sims as being CPU limited, indeed I only got a ~20% framerate increase when I went from a NV6800 to ATI 1950pro despite the new card having about twice the performace.
From what I remember, the PhysX card was good at collision detection, hence the tech demo showing a stack of boxes falling and interacting with one another. GPU based collision detection could improve the framerate at critical moments ( High anti-aircraft fire rates, Bomb fragments, Many firing aircraft with many damage hit boxes ).
True you would have a trade off with the look of the sim, but with the rate of change in the graphics cards you may not have long to wait before ALL settings are maxed out again.
