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.
