Computer Processor/ Bus Speed Question.

As a general rule, it doesn't matter how fast the actual processor speed is or what the bus speed is, as the limiting factor is always going to be how fast can the CD unit supply information that the computer is asking for. So therefore if the CD unit takes three seconds to start supplying data on a computer put together two weeks ago, it will still take three seconds on a computer put together 18 months ago.
It is possible to get newer style CD units that take advantage of higher transfer speeds, but again this is only a theoretical maximum as the physical units themselves are not able to spin that fast yet.
The actual speed of the processor is worked out by multiplying the bus speed by a multiplier, which is different for each processor model. So therefore a 3.2Ghz processor has a multiplier of 4 (800x4=3200). Regardless of this, as I stated above, transfer speeds from the CD unit to the hard drive bear no resembalance to the speed of the processor itself unless its being tied up doing something else that is resource-heavy (this will of course make copying from the CD slower). So under idle conditions, the speed of the drive transfer is as good as it gets.
