Hey guys, as you know the only update possible for the high end 27" iMac at the moment is the core i7-870 which only offers a minor speed bump. Now I am going to patiently hold out for an update (at least for the graphics) but I decided to do a bit of research and came across the Sandy Bridge architecture: Now I was wondering what you guys think the upgrade performance-wise will be to Sandy Bridge? I have a 2.8 GHz Core 2 Duo 24" iMac at the moment and have read in articles that the jump from this to the i7 isn't that big, but that the jump from the i7 to Sandy Bridge will be huge. What do you guys think? And jump in performance in this questions is not including power efficiency. As you can see from the table on the following page... http://en.wikipedia.org/wiki/Intel_Sandy_Bridge_(microarchitecture) ...the iMac could include the Sandy Bridge-MB processors which are due for release Q4 2010. Bearing in mind that Apple didn't include the i7 in the iMac until a year after release (I think), when do you guys think we could expect the iMac Sandy Bridge? Happy speculating!
