AMD Athlon 2000XP running at 1.7 Ghz, no overclocking...
AMD Duron 700 MHz, no overclocking...
PENTIUM II 500 MHZ, no overclocking...
I've given up upgrading for the moment... I plan to keep my computer till it sputters it's last sput, as it is fast enough to use for multitrack recording, and to simulate the Apollo Landings on with no Frame glitches...
