40MHz is plenty for doom.

Ew, no. Even 386DX-40 is terrible for Doom:

486SX-33 is certainly playable, but you really want 486DX2/66:

Doom Timedemo - 486DX2/66MHz

Edit: grammar

Edit 2: These videos are accurate, btw. I upgraded from 386SX-25 to 486SX-33 just for Doom while my friend got the 486DX2/66 Packard Bell. Envy.

Edit 3: My memory forced me to go back and properly designate the models.
