Good info.  Clears up a little muddy water.

I do have Nvidia and I use the Nvidia drivers.  Thought about using the
ones in the kernel but just never did.  I don't think it is the video
card tho.  I think some of it is all the hard drives I have installed
and that they are busy.  I run torrent software all the time.  It stays
very busy.  I actually set the connection speed to a little lower so
that I have some network speed that isn't being used so that when I do
something, I get some network bandwidth.  Plus, there's that growing
software problem that always exists.  Software rarely shrinks.

Generally, I use about 20 to 25GBs of RAM.  Mostly, Seamonkey, Firefox
and the torrent software.

Either way, the age of my current rig is a big reason I want to build a
new one.  It's getting a lot of gray hairs.
