XP still kicks WIN 7 ASS


Conclusion
Those who have older machines and were clinging to the hope that 7 might improve your one last time - forget it. In my case, at least, the software and just isn't there - the new OS resulted in massive performance losses. Whether or not newer hardware will show the same I've still yet to find (see my other thread), so who to blame for the performance loss is a little unkown right now. It could be bad AGP drivers (which are notoriously so) or just as likely be the new OS. I'll update after the other test on newer hardware is complete!

Conclusion
Windows 7 shows notable gains in Unreal engine based games, and some pretty heavy losses in the COD series. The Source engine based game results should be taken with a grain of salt - I had considerable trouble getting the games to not crash on entry (anyone with the looping audio problem knows how frustrating it can be). Standard multimedia and file based applications are notably faster, though more professional apps (Sonar) are still lacking. I'd imagine this is all because of drivers - but they should improve over time.

On Tom's Hardware is a post about Win 7 upgrade from Vista to Win 7 did not go so good.

If you want Win 7
I would get a new HD and get then get the Win 7 Pro or higher and install

Good Luck

Doz staying XP
