The result is a game that is much more fluid, doesn't stutter or lag, and the frame times are vastly more consistent. I don't know why people are saying that 1600 is just as fast as 2133/etc, when they haven't actually spent time testing. The difficulty in testing is that the games have to be actually played, using a set area for a set time and followingas cconsistent a path as possible, because using pre-rendered benchmark sequences don't tax the memory due to the AI and similar algorithms being preset and not dynamic. This is also likely to be the reason that benchmarks like 3DMark and Heaven don't see a gain, at least not much of one, from better memory, although 3DMark will show a gain in the dynamic Physics score.
The sweet spot, from my testing, for "off the shelf" RAM is DDR3-2133 with good timings. I use GSkill Ripjaws Z 2133CL9 to great effect, and the immense flexibility of the memory means I can test at a great variety of speeds and timings, thus reducing the variable that multiple kits of memory would introduce. I run my memory as high as 2360 9-10-10-27 1T 1.6875v for gaming and I have difficulty using 1600 even @ 7-7-7-15 timings due to how much more stuttering there is.
Please, try this yourself. The biggest difference is in modern first person shooters like Far Cry 3, but real time strategy games also show quite a big difference...
As for the Corsair Dominator Platinum, it's a complete waste of money unless you are buying the 3000 kit for LN2 benching, and the slower kits are truly a waste of money when a kit of Ripjaws Z, Trident X, Kingston (xxxx), and a few others will overclock significantly better, provide far more flexibility, and do so at 1/3rd the cost.
RAM is important, and fast memory is great to how, but this is one of those things where paying more DOES NOT get you better quality, in fact the kits of Dom PlatII've used have all been some of the absolute worst clocking memory I've ever seen, struggling and usually failing to achieve even a 100Mhz OC (effective; just 50mhz actual)!
