Do yourself a huge favour and don't buy another PC at all.  Get a Mac.  I have used PCs since 1976 and was in the PC business from 1978-2000.  I bought a PowerMac in 2004 to replace my old PC and all I can say is that I will never own another PC that uses a Microsoft operating system again.  I am so much happier with the overall PC experience (buying, set-up, day-to-day usage).  I bought an Apple iBook laptop off eBay in January for my wife and even though it's several years old and I have the newest OSX version on it, it runs great.  I could not, in all conscience, read that you want to go further down the road to PC hell without steering you to greener pastures.
