A faster CPU is not really an option.  Single threaded software decoding 
of H264 content at BluRay bitrates is impossible, and considering CPU 
development has been towards more cores instead of faster cores, it will 
likely remain that way for some time to come.  The fact that you could 
play Bruno on a dual core with plenty of spare CPU means that movie is 
rather sub-par.

Considering you have a C2D, you almost certainly have an available PCIe 
slot.  VDPAU capable cards can be picked up for as low as $20 after rebate.
