Only if you write a version of DOOM that uses the FPU as DOOM does not make use of floating point maths. :-)
Quake1 is a different matter and dose use floating point maths and so requires a CPU with an FPU but as an 030 would not be upto running quake1 if Clickbooms Quake port running on my 040 card is anything to go by.
