I would add that it also depends on what you're trying to do. A couple of P4 figures should be fine. Trying two or three Millenium fugires with high-res textures, props, etc. and you're going to be hitting resource limits. I'd ditch '98 and go to XP or 2000. Many people have had problems with '98. It doesn't handle memory as well, no matter how much you have. Upgrading the OS will pretty much require you to up the RAM as well. Go for 256MB minimum, more if you can afford it. Get a new hard drive. You can find 60GB drives for under $100 at places like TigerDirect. Install XP/200 on the new drive and you can still have '98 on the old one if you need it. If you can afford a new CPU/motherboard, go for it but I think the OS/memory/drive are more likely to fix the problems. Having said that, the 500MHz Celeron is a tad underpowered by today's standards. A 1+GHz Athlon or Pentium would get you a big speed boost across the board.
