I was more looking at 8GB per stick. If I place that in to begin with, I am sure it will be great. As either future developments or many years progress; the option to add extra 32GB is available, if ever needed.
Budget is not a key concern right now, as I am sure can be seen with some of the parts included.
Would you both say the RipjawsZ, because their availability is lessening when compared to the TridentX; albeit I acknowledge the great works of Newegg in always being on top of the game, and stocking the needed parts.
What would be the difference in performance between the RipjawZ and TridentX?
Also quick check, are NewEgg prices final or do they charge state tax?
The extra memory channels on the X79 platform are primarily intended to compliment the 40 PCIe 3.0 lanes. Seeing as a quad core SandyBridge can't even saturate 2 channels at DDR3-1600 (anything higher offers extremely small marginal gains), it stands to reason that a hex core SandyBridge-E on its own wouldn't either. In order to fully utilize the bandwidth provided by 4 interleaved channels running at DDR3-1600 you would have to be running highly optimized OpenCL code on 4 7970s and even that constraint is heavily alleviated by the 7900 series onboard memory. The amount of installed memory is far more important than the IO bus speed because returns diminish very quickly beyond DDR3-1333 and are almost non-existent beyond DDR3-1600.
