I've been using Knoppix for quite some time now, but really only on my older, expendable machines with nothing above a Pentium III, or an Athlon XP 1400+ in my current machine. I've bought some hardware for a new machine I plan to build, but before I buy a motherboard or processor I was curious about one thing: is Knoppix and Debian Linux compatible with x86-64 architecture? Reason being was because I wanted to give an Athlon 64 X2 a shot this time, but before I spend $400 or more on a processor alone, I'd just like to know if Knoppix will run on 64-bit technology. Everything I've used until now is x86, so 64-bit CPUs are entirely new to me.
