Bobby, agreed useless in so far as gaming, but for geostatistical modeling
of a disease outbreak (as with data kriging) and radiologic modeling where
you are trying to visualize an animated image while the calculation is
occurring rather than waiting for all calculations to be done then just see
a static image, I would disagree. If one never manipulates animation or
requires a 3-D picture of a moving function then these things would seem
useless. But to again agree with you, it simply depends on what you are
doing. To ask how dramatically does the AMD or Intel chip differ in handling
floating points, integer operations, square roots, the oddity is that in
some sense benchmarks are more tricky than ever to generalize because  both
AMD and Intel are changing their nomenclature with regards to chip speed.
The AMD chip called itself "3000+" because it could go faster on many points
than a 3 Gig, but the AMD actually had fewer than 3 Gigs because the AMD
accomplishes more per hertz. You can see some one Gigs go faster than a 3
Gig because of a different type of Pentium, front side bus speed, how faster
it is going to communicate with the RAM and peripheral devices. Now Intel
has followed suite and is in the middle of changing its chip nomenclature
system (viz. 325, 500, 700).

I hate to say this, it's so obvious, but...

Gaming and 3D benchmarks are irrelevant to the question of which machine is
faster when running Mathematica--or anything useful, for that matter.
