How comparable are these video cards to each other? How much better is the GT better than the GS?
 
Depends on exactly how you compare them.

For most three-dimensional applications, like games, the 8800 GT renders roughly 10-20% more frames over a given duration than the 8800 GS (see this analysis for more information).

However, for Pro Apps the GS is surprisingly superior (according to this analysis). I guess Apple/Nvidia must've optimized it for Core Image operations a little more than the GT.

As for how they technically compare, here's what the 8800 GT has:
  • 112 stream processors
  • 600MHz core clock speed
  • 900MHz memory speed
  • 256-bit memory interface
  • up to 512MB GDDR3 video memory

And the iMac's 8800 GS is technically a rebranded 8800M GTS (according to at least one source; iMacs use notebook components, after all). The specs for this card are:
  • 64 stream processors
  • 500MHz core clock speed
  • 800MHz memory speed
  • 256-bit memory interface
  • up to 512MB GDDR3 video memory
