Why does AMD call the athlon 3200+ or whatever using the +.. Like my 64 3200+ and then they say it is 2Ghz. Why not just a 64 2Ghz. Is the amd speeds calculated differently or what?

Because the mass market only sees clock speed. If AMD were to market their processors by clock speed, people would think they're slower than Intel processors, which couldn't be farther from the truth due to AMD's IPC. That being said, AMD devised a model system to demonstrate the relative performance of the processor.

Intel Core i7 860
Corsair HX650W
Corsair XMS DDR3-1333 (4GB @ 8-8-8-24)
Sapphire Radeon HD 6870
Western Digital VelociRaptor 300GB
Western Digital Caviar Black 1TB

In order to facilitate comparability of different Processors according to their performance(NOT raw clockspeed), AMD introduced a 'Quantispeed' ">'-rating for their processors.

Since an Athlon 64 can do more work per clock-cycle than a P4, it will perform about equal or better than a much higher clocked P4 even tho it is only clocked at 2.0GHz - hence the 3200+ rating.
This is because basically, intel's 'Netburst'-architecture(what the P4 is based on) sacrifices efficiency in order to be able to attain high clockspeeds.

Here's' "> AMD's Processor Performance Evaluation Guide.
It will give you an idea about how this rating works

I like to think of it this way

Intel = 2 cycle weed eater motor
AMD = Chevy V8 350

while the weed eater is hittin 20,000 rpms to hit a speed of say 60mph
the v8 hits 60 mph cruising at 1,500 rpms.

they both achieve their goal, but i prefer a V8 myself.
