Marco,

I'm running a cluster of 64-bit HP xw8600 Workstations each with 8 cores and 16 GB physical ram, high-end graphics adapter, 2x300GB hard drives running WinXP Professional x64 Edition and 64-bit Matlab.

The only advantage I see is the additional memory address space. We can work with somewhat larger files but nothing spectacular. Speed is not dramatically increased.

I'm not very impressed. 

A few years ago at a hedge fund I had clients hitting my Matlab apps on a 32-bit Linux box that seemed much faster.

Anecdotal input at best but that has been my experience.
