WebApr 12, 2012 · One note on processor speeds: be wary of paying a lot more for a very slight increase in speed. I’ve seen 3.2GHz computers sell for twice as much as 3.0GHz computers, simply because they’re “top of the line”. However, when you take a look at the math, a “top of the line” 3.2GHz CPU is only 7 percent faster than a 3.0GHz CPU. Websimulator.
