The 4800+ X2 clocks at exactly the same speed as an A64 4000+ and

You won't NEED it, just like you don't need SLI, but future games WILL
be programmed to run faster with the second (or more) core. If the
capability is there.... developers WILL use it -- particularly those
writing high-performance FPS-style games. You did note from my
posting that you can buy a dual-core compatible MB,( or in the case of
AMD, you may already have one ) install a single-core processor and
upgrade to dual-core completely at your convenience/price-point ?

Suppose that I told you that there was a physics accelerator for games
called PhysX that could be used as a co-processor for games that
supported it. Would you be interested (assuming price was no object)?
Well, the same functions can be emulated with somewhat less efficiency
on the second core of the dual-core without any need of an add-on
board. In the case of AMD just plug an X2 in. Games developers WILL
take advantage of the 2nd-core in a similar ( not necessarily as
simplistic as I have outlined ) way once they are commonly available.
Please note that between AMD and Intel, probably at least 1 million
dual-core desk-top systems and upgrade CPUs will be shipped before
the end of 2005.
As for technical papers on dual-core - Google it...
Clock rates have hit the wall... CPU power consumption now
exponentially increases with clock-speed. So, the CPUs have
to grow wider, and the most advanced games will grow wider
( i.e: support multicore/parallel-processing) along with them.
