In general I would say yes (assuming the work can be distributed
evenly). Multiple systems means you have duplication of more system
components such as L1/L2 cache, FSB, drive controllers. However, you pay
for the extra hardware. 

Resource contention for L1/L2 cache can be a significant bottleneck.
Unfortunately its not easy to analyze... Proper use of SSE can mitigate
the problem with streaming media applications by explicitly handling
transient data. Not sure how well PD/Gem/etc will handle this.

Also I would consider the relevance of graphics acceleration to the
task. Some things benefit greatly from the GPU, others do not, such as
particle systems.

Here is a system which I have used which is small, reasonably quiet and
reasonably priced:


I don't think its any louder than my laptop and is small enough to fit
in a backpack.
