 At the risk of being snarky, how about you stop that P2P file sharing 
 client?  amuled?!!?  Also what is that "tranmission-d" app that's using 
 a lot of your cycles?

 I run IONs with 2X1GB sticks and 512MB allocated to GPU.  It's not 
 perfect at the most demanding content, but I've made my peace with it.  
 I cannot imagine that RAM is your problem.

 It's not been feasible in my experience to run much else that the Myth 
 software on the frontend when you want VPDAU and quality audio output.  
 The problem being that some file formats and their codecs impose other 
 demands upon CPU while others play nicely with VDPAU and your favorite 
 audio drivers.  I wouldn't run other apps like you've shown.

 I haven't followed the bulk of this specific thread, have you also made 
 sure your xorg.conf contains these values?
