Yeah. I did get a new one last year, reason why, was my P4 2.4Ghz was to old, and I feared it was going to die on me. But it was woring perfect, and ran WinXp great. I needed to play decent games, but most of all play .mkv BluRay and other things, my P4 wasn't up to the task.
But I only upgraded to C2D 3.0Ghz, becaus it was way cheaper, becaus I got a lot of stuff second hand. And I had SATA harddives and some other stuff I got earlier so no need to waste money. I think this PC is going to last more than 5 years this time too.
