- Time out. We began this discussion first about 387 math coprocessors,
- then it changed into SX vs DX. An overdrive
- chip is not a math coprocessor, but it is installed in the coprocessor slot.
- As far as I know, it can be used on a SX or DX, but
- I don't know much about them, other than that propoganda film that Intel
- puts out, but I would have to say that whether a graphics accelarator
- speeds it up more than an overdrive chip would be purely application depen-
- dent. On the other hand, an overdrive chip would speed up all apps, DOS or
- Windows, while a graphics card would only affect Windows and graphics
- packages.
