Gwahaha @ ut2k4! You should see it on a dual opteron machine with a gig of dual-channel ram then.
I definitely DISrecommend slackware, particularly for a new-to-linux user. Reasons: installer isn't great, there's no built-in package management system for easily updating your software, many things have to be compiled from scratch (PITA for a new user), other things along those lines.
You have to be wary, though - distributions for linux geeks are like styles for martial artists - every one will insist his is the REAL ULTIMATE one, and everybody else's sucks.
Mandrake is OK, Fedora/Redhat is OK, SuSE is OK.
Slackware and Gentoo tend to attract geeks with too much time and too many extra cpu cycles on their hands.
Oh, and Debian is the REAL ULTIMATE. But the installer isn't so friendly.
BTW, I'm still waiting for my doom3 linux binaries to be released, and trying to get the windows ver running under emulation in the meantime.
Cut the tiny testicles off of both of these rich, out-of-touch sumbiches, crush kill and destroy the Electoral College, wipe clean from the Earth the stain of our corrupt politicians, and elect me as the new president. --Vash
