From what I have read the GTX 680m uses nVidia's new "Kepler" architecture while the GTX 675m uses the old "Fermi" architecture. So that means that the Kepler card is only available on the most powerful setup. Does anybody know the difference in the cards benchmarks? as there seems to be a few versions of the cards some having 1.5 gig of ram. I would not know if you would see any major benefits in the high end card unless you were gaming, I don't know if you would see any difference in Autodesk Revit or Solidworks?

675MX is in the high end 2012 27". That chip is Kepler based, unlike 675M. Confusing for sure. This site is helpful, but has yet to add benchmark numbers for the 680MX though their notes make it sound like it'll be about 1.5x as fast as the 675MX.
