Before you buy a new proc you might as well overclock the one you have 
to see if that _really_ is the problem.  Honestly I would be shocked if 
it was - unless you're trying to watch mpg4.  I have a frontend with a 
1700+ (1.4GHz) in it and a radeon 9600 with the free open source 
drivers.  It can do 640x480 at 7500KBps with no stuttering and about 30% 
usage (this is without any video acceleration like xvmc).  If you have 
40% usage I would be in doubt of the processor being the problem.  For 
real time jpeg, which I was using a few months ago, it has the same 
usage.  Also, 480x480 mpg4 was working well with 50% usage or something 
a little below that.  Maybe you have too much traffic on your network; 
are you using wireless (it works fine for me but drivers could be a 
hidden problem)?
Also, I had major stuttering using TVout on my old 9600pro until I got 
the fglrx drivers and XV working.  However, it was obvious where the 
problem was because the processor was pegged at 100%, which told me the 
problem was the graphics card, not the processor of course.
