There are two issues here.  Creating threads and switching between
threads.  The new scheduler and pthread library is supposed to help.
http://kerneltrap.org/node.php?id=3D422

For some anecdotal, non-scientific impressions.  My friend and I both
run Gentoo boxes with comparable processors and RAM.  Gentoo provides
2.4 kernel sources with the new scheduler patched in.  I use the new
scheduler my friend does not.  I don't have to fool around with nice and
renice when I'm compiling apps in the background.  KDE is still
responsive when top claims that the CPU is running at 100%.

However, this is on the desktop and I get the impression that you will
be using this box as a server.

Apache claims that they can fill a 10Mbps connection with something
ridiculously slow as a P133.  But you'll need something faster if you're
gonna use php, perl or something else.

Being in the game industry, there are advantages in choosing Linux.  You
can run UT and Quake servers.

Sorry, that I couldn't be more helpful.  What services are you wanting
to run?
