SVI something or another... had 2x 5 1/4" floppy drives, and no HDD!
80286 (8 MHz I think)
80386 (SX-33)
Pentium 166 MHz
Pentium 233 MHz (was in a Mitac laptop)
Celeron 500 MHz
Celeron 800 MHz (first PC I built myself)
Duron 1.2 GHz
Pentium 4 2.4B GHz
Pentium 4 2.66 GHz
Pentium 4 2.8C GHz
Everything from (and including) the Celeron 800 I built myself...
As can be seen, I've used one or 2 Intel CPU's in my time...
(In addition to the above lot, I also about a year back built up an old Pentium III 850 MHz rig, to serve as my Win98 machine [for the older games...].)
Hopefully my next CPU should be a A64 3200+...
