Hey, I'm running Fedora Core 4 (runs doom3 flawlessly), I've tried some other but for now as far as I have tried others Fedora works best for what I do I heard Mandrake and Knoppix are two good ones Fedora Core: http://fedora.redhat.com/ Also suggest Libranet if you want an olides style, lol I suggest you ignore Linspire, lol I got it for free using their order coupon, plus they hav some CNR thing that you gotta also pay $50 for and you can't disable, really annoying, the pros to it are, pretty gui , and you can see all your partitions/hard drives without having to set it up http://slickdeals.net (if you want to try linspire look in the old deals for Linspire coupon gets you the $50 thing free)
