huh? You plainly have never spent much time tweaking multimedia stuff have 
you? You build those to get the most performance out of your software from 
the porocessor to allow them to take advantage of the special features that 
varies between AMD and Intel chips, such as SSE, SSE2 and 3D-Now. Your 
argument about I/O is something you cannot take into account since that 
relies on the type of discs/ram you have in your system. Your comment about 
being in user space is invalid too, since apps rely on the kernel-executive 
to run (kernel, glibc) thus optimising these gets the desired added 
performance for most graphics design/multimedia workstations.
