Alright.... we're finally getting somewhere. For my 27" imac I had completely ruled out the C2D, and was going to order an i5 with 4GB ram, and add 4 additional GB myself at a future date... Now that the i7 benchmarks have been posted, the results look like it may well be worth the extra $200. Not that the i5 is too shabby, but the i7 does look significantly more powerful. What are other people's thoughts? Both computers are completely overkill for my needs, but I plan on using it for a long time (currently using a imac G5 rev B... nearing 5 years on it).
