So I just came from the apple store here in Denver. I spoke with a very knowledgeable man that said that he has ran geek bench tests on the 15" 2.4 i5 15" 2.53 i5 and the 15" 2.66 i7 and came up with these numbers He said the lower model one was 30% faster than the high end 2.8 c2D mbp last update. He also stated that the 2.53 was 8% faster than the lower model, and the i7 was 13.5 percent faster than the lower model and about 5.5 percent faster than the 2.53. So in the end the new high end model 15 is 44% faster than the late 2009 high end. Thats is some really good numbers granted I am still dissapointed with the gpu choice. I thought about getting the 2.4 and upping the ram to 8gb and an AG hiRes screen, but actually ended up getting the 2.66 AG hiRes ( i guess it was immediate satisfaction that drove me to getting it and possible resale value in the future if I want something different) So now the next upgrade...8gb of ram ... Should hopefully not have any problems with C4D or AE considering my early 2008 2.4 runs both fairly decent with the 4gb of ram and is probably about 70-100%(just a guess) slower than my new i7. If you are looking for the most bang for your buck...get the 2.4 and max the memory out...that machine would be a screamer.
