I am curious to know some thoughts from folks about the pending Silicon chip-powered Mac Pro and its impact on the intel-based Mac Pro 7,1. I am thinking of upgrading from current Mac Pro to next one but in terms of performance I was wondering if getting 7,1 be worth getting or would it be not worth it if there is Silicon (8,1) Mac Pro. If there is a Silcion Mac Pro would the 7,1 be worth it or somewhat pointless?
