cpus are running fine.  during program start, (OO or other) cpu usage 
spikes but then settles down.  It is entirely livable as is, without the 
extra ram.  Only problem now is things like Tux Type and Tux Math.  They 
seem to bog down system horribly.  They are graphics intensive, but as 
everything else is acceptable, why them?  10/100 nics everywhere, and 
10/100 switches.  Because of the server motherboard switch, 1 of its 
nics is a Gig one, but it is plugging into a 10/100 switch so is unused 
to its potential

Question.  Will getting a Gig switch that the server will plug into, 
along with a line from the other 10/100 switches do anything?  I mean, 
if only the server has Gig nic, what good would it accomplish if I 
cannot afford to put gig switches and nics everywhere?  I have truly 
blown the budget for this year.  I might be able to squeeze out a small 
gig switch, but what good is it?
