I use both Macs and PC's My main everyday system: Apple PowerMac G4 DP450, 1GB RAM, ATI 8500 AGP, 120GB 7200 HD. Mac OSX 10.2.4, Apple 17" Studio Display (CRT). This is the main system I use C2 on, and is very speedy even as compared to the other PC's on my desktop: A 2.54 GHZ P4 with 512MB RAM, Geforce 4 Ti 4400 with 128mb VRAM and Windows XP Pro. This is a very quick system, but for everyday use, the Mac is more then fine and is allot less trouble not too mention more fun to use. The PC does excell for games and Mojoworld though. I also have a Cube type PC with a P4 1.8Ghz and 512MB RAM I use as a domain controller and a server. It is a shuttleX pc, and for its size (about 5" high X 11" deep X 7" wide) is complete, even sporting an AGP slot and a Heat Pipe cooling system that is quieter then any PC in my studio. This would be an awesome system for 3D rendering, they also make a AMD compatiable version as well. The caveat of these systems is you have to buy them custom built from a local dealer. They don't offer pre-configured units. If you are interested, though, contact me off list as I have sources and the ability to custom configure a system up to a P4 3.06 Ghz.... All in all, I choose the Mac because of its elegence, trouble free operation and it's UNIX underpinnings. But I could totally understand why you would want to jump ship to a PC. The current macs are not as fast as the current PC's. However I have heard, from reliable sources, that Apple will be releasing a completly new system architechture utilizing a new CPU that will once again leapfrog the Wintel world... Stay tuned, I hear that a July to early fall rollout is likely
