In my opinion, yes. Personally I still believe that if you want a really clean lean sweet running machine it needs to be repartitioned, reinstall OS yearly. Helps of course if you have all the drivers you need, along with a few other things.
For example I prefer Western Digital drives, so I keep a couple of copys of WD utilities around. They let me boot from the CD, install the drive, copy or mirror it, repartition it, reformat it, etc.
Then reboot with the XP cd, rock and roll through that, install mboard drivers, then video card, and all thats left is software. Firefox & Thunderbird, Glary Utilities for managing startup menu and processes, threatfire, then AH, and any other games.
If you take the time to backup ahead of time, and have drivers downloaded, or the original disks it only takes me about 4 - 5 hours to do a full clean and reinstall, and get back to where I was.
