Hi, everyone. I have two computer with different processor and RAM 1st Intel Pentium 4 2.66Ghz 256RAM 2nd Intel Pentium M 1.73Ghz 512RAM I heard that upgrade RAM will make more faster. In games, i fell that the 1st pc faster than 2nd one. But my 2nd PC's RAM higher than my 1st one. Is Processor also affect the PC speed ?
