A few quick questions abut using more than 16GB of RAM in the 27 inch iMac. To begin, I know that I need more than 16GB for sure. I use a Mac Pro at work that has 16GB and page outs are at about 5GB after a day's work. I'll be putting my personal machine up to a similar load with all of the same software. This leads me to believe that I need more than 16, but probably less than 32. I'd like to not spend more money than I need to. So, let's assume that the new iMac can accommodate 32GB and comes with 8GB standard, in a 2x4 GB configuration. Will it work to just buy 2 8GB sticks for a total of 24GB including the memory it came with? Is mixing brands and different sized sticks an issue? If not, is there a certain way that I want to arrange them in the 4 slots that the iMac has? Unrelated, but does the iMac come with a thunderbolt to VGA/DVI adaptor? Thanks for any help that you may be able to provide.
