Sandy/Ivy Bridge won't come into play at all if your using an Nvidia GPU
with VDPAU, you can use just about any CPU.  The only way the processor may
make a difference is if you were using VAAPI with the Sandy/Ivy bridge
processor's built in graphics processor.  VAAPI is supported, however it is
not as refined a solution as VDPAU.

Go with the cheaper processor and at least an GT430 for the optimal support
(make sure you have 96+ cuda cores on the nvidia GPU; so no 420/520/610
even though the model numbers are higher)

My recommended build is a good Ivy Bridge capable motherboard, cheap $45
Celeron G540 CPU, and 4-8GB of RAM.  Coupled with a Nvidia GPU and VDPAU
you will have excellent performance today and an easy path for upgrades
when CPU/RAM prices drop.
