I have the 8MHz version and recently upped the cache to 64k. Don't bother with
a larger cache, 16k is good enough for most of the current crop of programs.
Within a couple decimals points, there is no difference in speed. I estimate
that 8Mhz has an effective speed of 7.7MHz, if ther is no I/O, with 16k and
7.8MHz with 64k.

The big loser is 8k, effective speed is less than 6MHz. The benchmakrs used
are very rough at this point, SHRConvert GIFs, a few games, some Orca
compilers. None have any noticable improvement over 16k. 

The speed improvement does give you close to 25% speed increase right out of
the box, but the cost is much higher.

Orca/C has a number of standard benchmarks included in source form, once
compiled this may give a more scientific appraisal of speed differentials, or
it may not. I don't care how fast the GS does a benchmark, benchmarks aren't
much fun.
