One opinion: my brother had WinXP 32Bit on the machine, now he has Vista 32Bit. The very same hardware underneath. All own games, all commercial games, all benchmarks, any apps run less than half the speed the used to run before. We profiled our games a bit, DirectX calls seem to need about three times more time to execute than before. But it doesn't explain why a release build now takes about ten minutes when the very same project (ours) on the very same hardware (Athlon 3200+, 2GB, GF7800GT) and the very same compiler (VC2005 Prof) used to take less than three minutes before.
The Aero GUI is another point that costs some performance but it's not that much and you regain it when running the application in fullscreen.
This opinion is by no means representative. Yet it's frustrating. We had some hopes when Microsoft announced they solved a mysterious bug that costed so much gaming performance, but applying the hotfix didn't change a thing. Thus I suggest avoiding Vista. Give it some more time to mature.
Update your disk controller/chipset drivers. I had a comparable system (Nforce 4 motherboard), and disk performance quadrupled(*) as soon as I installed the latest drivers from Nvidia (released this month, I think).
(*) slight overstatement, but the difference was *huge* - compile times went down, and everything became *much* more responsive. Worth a try.

Ive also read that the opengl driver for vista is really bad. Is this fixed in the sp1 update also?
Im thinking now i should wait a while, and see how this turns out.
The opengl vista driver..? Well, the opengl XP driver sucked more (software rendering vs D3D emulation on Vista). As long as you install drivers for your graphics card, you will have native OpenGL support which is as fast as on XP. Never had a problem with graphics drivers, and I've been using Vista since beta 2.
