schadow1, you upgrade the processor every few months?! Isn't it there's generally little difference between, say, a 1ghz vs 1.2ghz vs 1.33ghz?
I prefer upgrading when there's a pretty big difference in speed. (Based on my actual upgrade, it seems my upgrade occurs when there's approximately a 7x speed increase compared to my previous processor):
1986/12: 6502 @1.023mhz (Apple ][+ clone)
1989/11: 80286-12mhz
1992/11: 80486DX-33mhz
1997/5: Pentium MMX 166mhz
2002/9: Pentium-4 1.80A ghz
