When it came time to upgrade my Dell from a 486DX33, I picked a DX4/100 overdrive (with the funky voltage converter) because all the clones looked so scary*. It cost a little more but I've had zero (0) problems with it, and it's doubled the speed for compiles. * See the PC Chip List FAQ (pc-hardware-faq/chiplist) to see the bewildering variety of options to pick from (cache size, bugs, voltage, pinouts, etc).
