I have a gateway laptop currently running iPC 10.5.6, most stuff works great but it has this older intel GPU (8xx series) that only worked in 10.4.1. How realistic would it be to try running such an early version of the OS? I really want a functioning GPU. Its a Pentium M running Voodoo v. 9.5 currently with Chamelion 2.0, Drivers for audio, USB, PS2 trackpad and Keyboard, all from iPC work fine now in 10.5.6. Its just the dumb GPU.

hmm... well Tiger is pretty much ancient now, but personally, I would stick with 10.5.6. But if it's complete system compatibility you would like then go for Tiger, but be aware that most apps only work on 10.5.* these days.
