schloss_1 - I'm using a year old DELL P4, 2.26 gig, 512 of RDRAM, 80 gig hard drive, XP, 19" Trinitron monitor and cable.
I went from a 200mmx, 64SRAM, 8 gig hard drive, Windows 98ME, with dial-up.
I've had no problems (other than self-inflicted) with it at all from day one.
Well, except for....I did have to strap myself in for the first couple of weeks due to the speed, lol.
