Scumbria, <You and Ten are both correct.> No, one of us
is much more correct than other. Ten is claiming
that higher SlotA bandwidth is of no use, and that
the memory bandwidth must match the CPU bus.
This could be true in old Socket-5 Intel days
when the simplicity of synchronous clocking
along busses was the state of the design art.
With clock-forwarding and sophisticated FIFOing this
is no longer the problem (except for Intel designers
who still could not master this according to the
recent snooping "errata" in all Pentium-II, III
etc.)

<A certain percentage of the time a computer spends
doing a task is processing time, and a certain percentage
is time spent waiting for memory/IO.>...
..and a certain percentage of this time is overlapped,
and a certain percentage is going to restart
pipelines after dependency resolution, and...., and....
:) :) Therefore, a blatant proclaiming the memory
as one and only one bottleneck is a bit of a stretch.
After all, faster CPU channel reduces its own latency
at least, and snoop response time. Therefore, hurray
to Athlon 200MHz bus that will kick Pentiums butt.
How about that?
