Athlon vs. Turion (Moblie Processors)?

Intel Core 2 Duo is the best choice. Intel manufacturers better mobile processors. AMD processors may be cheaper but they are certainly not as efficient as Intel. The difference in the Intel Core 2 Duo Processors is the speed which is listed in parentheses in GHz. The bigger the number the faster the processor. So a processor at 2.0 Ghz would be faster than the one at 1.4 GHz and the one at 2.5 GHz is going to be faster than the one at 2.1Ghz.
