How hard can it be to fully support 2012 GPU in a 2010 Mac Pro? How hard can it be to fully support GTX5xx and AMD 69xx in 2012 at least? Do I miss something or is it just the slap in your face Apple attitude? Why couldn't they tell the Pro community: "We wait for the 2013 Ivy Bridge Dual Xeon CPUs for a major redesign. Until then we upspec and lower the prices on the old Mac Pros and support as much as we can on the old platform." Can someone enlight me?
