Here a question on memory. I am planning on buying a new 12 core mac. I can afford to go for much memory and don't need it anyway. I was going for the base 6Gb (6 x 1Gb units). I am wondering if it's worth going for the 8Gb (4 x 2Gb), as it is likely to be only a little bit extra money. This leaves more space for more memory if I decide to upgrade later. My question is does it help to spread the memory out in 1Gb units, or does it not matter if I go with (4x2gGb). Discounting the extra 2Gb, is 6x1Gb better than 3x2Gb?
