applekid said:You've got to be kidding me! My dad's 1.8 GHz P3 Laptop is horribly slow with Windows XP. It's a joke compared to my G4 iMac with 800 MHz. Once you turn on the computer, you have to wait a couple of minutes for the PC to be ready to do anything. You'll click, nothing happens, and you'll sit there for a couple of minutes until something moves. ...
I helped my friend purchase a $900 Dell PC about 6 months ago... a 2.8 GHz (I believe) P4 with 512 MB of RAM and a GeForceFX 5200 and Windows Home edition. Well, even his decent PC is a choppy mess. Windows, icons, buttons don't respond when they're expected to. ...
I haven't read to the end of the thread, so this may have been mentioned already. If so, sorry.
I'm not a Windoze fan, but often it's unresponsive because of spyware and/or viruses rather than underlying responsiveness. I suggest you download adaware (www.lavasoft.de) and Spybot (security.kolla.de) and AVG antivirus (www.grisoft.com) and make sure your dad's and friend's PCs are clean.
I still haven't got my PowerBook so I'm using my 2 yr old 1.8 GHz P4, and it's still pretty snappy, but I have 1GByte RAM, have turned off the eyecandy (i.e. configured it for performance) and I keep it clean of all (known) spyware and viruses.

As someone else said, also make sure all drivers are up-to-date, and go to www.pcpitstop.com and have it analyse the PCs. Also, run sandra (www.sisoftware.co.uk)
Sorry - this shouldn't really be in a build-a-Mac thread.
But, as to why anyone would want to build a PC/Mac rather than buy? I am tempted to build my own PC, just for the hell of it. But right now I'd rather save my cash for a PowerBook.
