well, if you mean the "AMD ATHLON XP 3200 "Barton", it is the 200Mhz fsb version of the Barton processor, running at 11x200Mhz, 2.2Ghz.
it is a good processor for sure, but I think most people here won't recommend it, because of the fact that it costs a lot ($450), and you can overclock a 2500+ to the exact same speed of a 3200+ quite often, and the 2500+ costs around $90.

but if you mean the "AMD Athlon 64 3200+", that's quite something else. This processor runs at 2Ghz, and actually costs a few dollars less than the Barton 3200.
this is the one of the newest products of AMD, the cheaper of the two processors that supports 64 bit operation.
it comes with a heatspreader like the P4 to protect the core, and it's what qwerty57 got to 27k+ 3DMarks with.
I think this is a much better processor than the Barton, but whether it justifies roughly $445? I'm not so sure. At the moment you can only run single channel DDR with this processor.
This is a nice processor, but I'd say wait for the 90nm, socket 939, 1MB cache, Dual DDR version to come out next year.
