Quake is playable only in low resolutions like 320x200 on a 100 MHz 486DX, I can't imagine playing it on a 33 MHz, though technically it should run.
I remember that I did make a lot of use of the FPU unit in my 486 (like 3D raytracing, some video watching) but who would use a 486 for such tasks today. Not fun.
And that was a 100 MHz.
But if I had a choice, I would take the DX version, of course.
If you replace an SX with a DX, just make sure it works as it should, e.g. try to start Quake and watch the slideshow 😀
