You need three to four PI2s to get into the
performance range of an old,
second hand 2-3GHz office machine. This doesn't make sense economically.
Sure it's fun.
Agreed.
My first thought was for chromeboxes with 1.6 bunny-fps and Intel, so
no fancy compiling needed.
Power consumption, size, scalability... are certainly advantages, but
not for only 0.3 fps
Let's see how it develops.
