WinXP SP2 Which Processor Driver?

[AlexanderT]

I noticed that Windows XP SP2 replaced the old PentiumM driver 'gv3.sys' with 'intelppm.sys'. Now, I have read somewhere that some users on this board reinstalled the older gv3.sys driver. I decided to live with the new driver for a bit - and haven't noticed any problems with it (yet).

What is your experience? Any reason why you would recommend me to reinstall gv3.sys?
