I'm not sure which one to take: the new, low-end 15" MBP with the 6750M gpu, or wait for the Ivy Bridge. If I wait for the Ivy Bridge, it would be because of the lower general battery consumption, be able to do more with the same battery cycle, as well as the better cooling (or less heat) the chip provides. This is, as I have heard one of the major bullet points of the Ivy Bridge. Only, I'm not sure what to expect. Of course, nobody knows, but some can make more accurate calculated guesses than others. So, can someone tell me how much hours more it would be expected, and how many °C cooler the MBP would be? Thanks.
