Dave, I did it, and can attest that Midnight Rider is right: you do need a good video card and at least a gig of RAM for it to run adequately. An ATI Radeon Pro will give decent performance, but no Core Image. Flashed fanless Nvidia 6200 cards are cheap, will speed up your system and give you access to all the visual candy Leopard has to bestow. (Their only caveat is a very long startup time, which can be avoided by disabling their thermal sensors.)
Robert is also right in that it will undoubtedly run slower than Tiger. In my personal experience, the difference wasn't too bad. For some reason, Leopard Assist didn't work in my case, so I had to do the firmware trick manually. Make sure your machine's firmware is up to date, though, or Leopard will NOT install at all. I don't remember if it was 4.1.9 or .4.2.8. Hope it helps.
