Idle question about multi-core processors

[walt]

[I confess, I'm not sure if this question is off-topic or not.]

I just read this blurb in an e-newsletter:

Advanced Micro Devices Inc. (AMD) launched a motherboard with four cores
on Thursday, targeting gaming enthusiasts in an effort to keep pace with
the release of quad-core chips by rival Intel Corp.

Well, I always read that the whole point of expensive graphics boards
is to take the workload off of the CPU.  And now, suddenly, the trend
is to provide more CPU's to attract the gamers?  Something here doesn't
add up.

In any case, it looks to me like the mass-market may be supporting SMP
mobo's much sooner than I suspected.  And, I suspect that DragonFly may
provide much better performance on SMP hardware than many other OS's.

Therefore, this post is not off topic at all.  QED  ;o)

My question (at last):  anyone care to provide a stream-of-consciousness
response to this post?
