However, you do pay a price if you're a gamester: namely, many games will not run under Windows 2000. If I had my druthers, I'd go with Linux, but not all of the major software packages have been ported to Linux yet, so I'm kinda stuck.
It's very possible there's a workaround for that. I use DOS Procomm (terminal program) and found a virtual device driver that lets it have direct hardware access to the serial port (normally not available under NT). Maybe there's something analogous for games.
Also, most of the games I have, either will fine on 2K Pro, or I can find a patch by the companies that make these games on their websites.
I hope this helps you.
