I still have my old 650MHz 128MB computer that runs XP Pro version 2001 no SP.
And it runs fast as, but the only software I have on it are the display, sound, NIC, modem drivers and uTorrent.
I use it for uTorrent, on a V.92 modem, don't ask why,
I just like it that way.
I use my fast computer (3.3GHz 8GB) and a fast satellite data link to connect to the Internet for normal stuff.
