It depends upon the game whether you see an improvement or not by "ripping" it to the HDD. Older games won't see as much of an improvement as games built to take installation into account; indeed, Bungie warned Halo 3 players that installing to the hard drive will actually increase load times due to the disc caching system they used to speed up reading from the DVD.
That being said, I put Fallout 3, Gears of War 2, and Mirror's Edge on my drive and noticed less pop-in and faster load times. Though Fallout seemed a bit "crashier" afterwards when coming back from quicksave...
The quieter and cooler running is a nice bonus, but if I don't see a performace boost after installation I'll just delete the image from my drive and run from the disc.
