I have a tough decision to make. I'm looking for a new computer before I go to college. I was going to build a PC for cheap, but the thought of Windows kept me from it. I can't help that I'm a Mac guy through and through. So I read about some people who took old G4s and upgraded them to make them pretty fast by todays standards. I was looking into that when I realized I wanted to build my own. I just couldn't get past the desire to "build my own computer." It just sounds right. So I read the article on Macopz.com. I've been talking to a few people. I think I want to build a G4 - though I might buy one cheap and upgrade. My question is, if I put all this effort and money(it's over $1100 if I get 1.5GHz processor) into this computer, is it going to be able to keep up for 3 or 4 years to come? Will new G4 upgrades be made so my system can stay fresh? Am I going to do all of this only to get lost in the new 64bit craze? Basically what I'm asking is - Is this investment going to last long enough to spend the money and time on it? Also, does anyone know the relation of MHz between Mac and PC? I know that Macs have lower "MHz" but aren't necessarily slower. Are there any benchmarks that show how the Mac MHz are faster than the PC MHz? Or is this even true? Thanks!
