Could a PC with an Intel Celeron run a game that requires an Intel Pentium III?
Possibly. "Celeron" doesn't refer to any particular processor. They are cost-reduced versions of the Intel Pentium II, Pentium III, Pentium 4, Pentium M, and Core 2 Duo. Assuming that your Celeron is based on a processor that is faster than the Pentium III, you shouldn't have any problems. If yours is based on the Pentium III, check the clock speed. A 1.2 GHz Celeron, for instance, is probably fast enough for a game that requires a 1 GHz Pentium III.Other factors, such as the graphics card of your system, may also be important.
