Could someone let me know what the main difference is between the Pentium III and Celeron's. I'm running a Pentium II 333mhz now. This board can handle a Pentium III 933mhz with a 100mhz bus. Due to the lack of money I can only spend about $75.00 right now. The Celeron 800mhz with a 100mhz bus is selling for around $60.00 right now. My question is, is it worth buying or not and is good for gaming. Thanks~
