I just noticed the new Westmere processors are for sale, and they're not that expensive. These are the ones I'm considering: http://ark.intel.com/Product.aspx?id=47921 (Xeon X5660) Any reason I shouldn't upgrade? I did notice today how much faster my Mac Pro is compared to my laptop (about 5x faster in video encodings). So that's hours of time. Would I benefit from this? I don't want a new Mac Pro (if they get updated) and if they did, I'm pretty sure it would cost like $7000 for the same configuration.
