    No. The difference is "threading". Intel CPUs show up as 2x their number
of physical cores and seem to behave that way. Either way, you will probably
end up spending about the same amount of money for the same level of performance
regardless of vendor.

    Also, different types of content seem to benefit more from parallelism. BDs
seem to top out at 2 cores/threads whereas DVDs manage to take advantage of as 
many cores or threads as you have available.
