If I remember the benchmark results correctly, the extra 32k speeds up video
by a few percent, and "Scientific" operations (IE floating point math) by a
few tens of percentage points.
I've got a 128k cache card and it speeds up everything by quite a bit.
Probably has something to do with the built-in video getting sped up.
