Right now im running an i7 920 hackintosh with a 64bit geekbench score of 9086. I want to get a real mac either an iMac i7 or the stock mac pro. Obviously besides just the build quality of the mac pro partnered up without having to worry about Sleep kexts and such would be a benefit but im guessing the speed would be about the same. which makes me wonder is it really worth spending $2500 for the same speed? I have considered the imac cause its a little cheaper and i would at least get a 27" display out of the deal. So my question is what would I expect to get speed wise out of the 3? I run protools do a little bit of video editing and I encode a lot of movies and stuff for my itunes library.
