Quote - Since it's multithreaded, all other things being similar, at least twice as fast if you have a dual core (probably faster).  You can turn on all the quality options and it'll take longer to render but if you want to just match what the P4 renderer can do, pretty safe to say at least twice as fast.

Thanks. That's exactly what I wanted to know. I think its probably time I upgraded anyway. It seems like everytime I am thinking about upgradiing they release an even newer version; everything just goes out of date so quickly.
