All, but Muchi Muchi Pork, Zeus hardware and the most demanding Vegas hardware games, ran 100% speed without hiccups on my G3258 overclocked to 4.8Ghz with only one core enabled.
With the recent optimizations of the cave1k core I think Muchi Muchi Pork will work full speed as well.
So, yeah, go for the cheapest, lowest core, highest clock processor you can find.
