I can't believe you put that together without liquid cooling (yet).
Congrats. You're the first on here (that I know of) to make the transition to DDR4. Although it's got some benefits, from what I've read for the average user there's nothing to be gained. Right now the noticeable
benefits of DDR4 over DDR3 are net 0, except that you're forced to use it with the newer CPUs.
DDR4 actually has higher latency rates (are slower) than the best DDR3 chips. Latencies are some where in the neighborhood of 15 to 16 for DDR4 vs 8 to 9 for a good DDR3 chip. It looks like the Gskill DDR4 that you have is at a latency of 15 with numbers of: 15-15-15-35.
I recently did a bit of research into this before upgrading my office laptop from 4GB @ 1600 MHz (11-11-11-28) to 8GB @ 1600 MHz (9-9-9-24)
The Frequency (Bandwidth) to Latency (Speed) relationship is inversely proportional. You sacrifice one for the other. I'd rather have faster RAM with a lower CAS latency than a higher frequency.
To make an apples to apples comparison and measure the true latency you have to convert to nanoseconds, just like the quarter mile time in my sig.
Here's the formula:
(CAS / Frequency (MHz)) × 1000 = X ns
The real Frequency rate is half the listed rate where, for example, 1600 Mhz is really 800 Mhz (1600 is the double in DDR).
For example, I'll compare my 16 GB DDR3 to your 16 GB DDR4.
DDR3 @ 2133 Mhz:
(10 / 1066 ) x 1000 = 9.38 ns
DDR4 @ 2400 Mhz:
(15 / 1200) x 1000 = 12.5 ns
My DDR3 RAM is 3.12 ns faster than your DDR4 ... As I said, net difference is so insignificant as to be near zero.
Here's the bigger difference:
16GB G.Skill DDR4 at 15-15-15-35 sells for $290
16GB Mushkin DDR3 at 10-12-12-28 sells for $77
If you're interested there's some interesting reading here: http://www.tomshardware.com/forum/28...ency-frequency
I'm curious what your previous system specks were? What are you upgrading from?
I'm also curious what you plan to do with all that computing power? Is it a gaming rig? If so what do you play?
I doubt that for other than bragging rights you're going to need more than the 16GB you have now or a CPU with more cores. IMHO you'd be wasting your money to buy more RAM.

DDR memory running at 1333mhz is effectively fast enough than for all but the most severely demanding users. It will never, ever be a bottleneck, at any latencies. When talking about making your PC perform, as far as the RAM goes, just buy decent name brand memory, and enough of it to do what you need to do.
BTW, Nice monitor / small TV.
What are your thoughts on Windows 10? I see that Microsoft will offer it for free for a year.
I'm looking to upgrade mine or add a second monitor some time this year. I'm also looking at the same GPU that you mentioned.
Congrats on your new system Ian. Now get some proper cooling on it!
