Hey!

I am completely new to computer building. In fact, a week ago I didn't know anything about most hardware you find around, let alone all of what seemed to be a complicated sight inside my old towers, ha ha. Given my disclaimer, please bear with me and my ignorence. I am trying to learn all I can as fast as possible! But, of course, I am left with some questions and ineptitudes.

My hope is that those with experience might answer a couple of my questions as well as look at the components I have chosen thus far and see if there are any other comments or recomendations they might offer! THank you in advance for any and all your help! All right, let's get started.

I am building two tower computers. I don't have all of the parts chosen for both machines, so I am just going to be putting what I have decided and split decisions at the end.

Computer 1: Normal MOffice work, heavy internet use, light gaming, stability, reliability, OC, versatility, future compatibility, and potential for longevity in the mid-range(5-15yrs).

Computer 2: For video editing, rendering, especially with high bit rate, and 4k raw editing and rendering, etc. For gaming, heavy OC, and any other more intensive application as well as potential to meet the demands of future applications and tasks.

Computer 1:

CPU: Intel i7 5960x Extreme Processor

Mobo: Asus LGA2011 v3 x99-E WS

Memory: CORSAIR DOMINATOR Platinum 16GB SDRAM DDR4 2666

GPU: PNY VCGGTX7702XPB-OC GTX 770 2GB OC 256-bit GDDR5

-Split Decisions-

PSU: CORSAIR AX1500i 1500W ATX12V Full Modular Power Supply80 PLUS Titanium

VERSUS CORSAIR AX1200i 1200W ATX12V v2.31 80 PLUS PLATINUM Full Modular

The idea here being, I have heard a bit of talk about power supplies with higher load expectations being rated for performance at those higher loads and below lower loads(I believe either 15, 20 or 25% I can't remember) they are not performance rated. I don't know the total wattage of this system yet, but I would like to know where the sweet spot lies for power performance and efficiency under heavy loads, while not limiting myself for future component additions and upgrades(considering all of the PCIe expansion available on the WS-E mobo!)

Computer 2:

CPU: Intel i7 5960x Extreme Processor

Mobo: Asus LGA2011 v3 ROG Rampage V Extreme x99

PSU: CORSAIR AX1500i 1500W ATX12V Full Modular Power Supply80 PLUS Titanium

-Split Decisions-

GPU: ASUS ROG MARS760-4GD5 GTX 760x2 4GB 512-Bit GDDR5

VERSUS ASUS MATRIX-GTX980-P-4GD5 GTX 980 4GB 256-Bit GDDR5

Keeping in mind that this machine is for video editing and rendering,the indecision comes from the 760 having 2304 Stream Processors/CC at 512bit rate and the 980 has 2048 Stream Processors/CC at 256bit rate. I had heard that for my purposes, more cuda cores are good because certain editing software will tap into those resources thus having an expanded capacity. I have also heard that with 4k video editing and rendering it will be benficial for the highest bit rate that is possible. But I have also heard that it makes no sense(from gaming review sites and others like it that are more oriented toward gaming) to buy below the current PBI if one can afford it. Since the 980 is a new PBI I just need to know if the benefits of having a few hundred extra cores, and a bit rate that is twice as large, will surpass the 980's PBI improvements. Also, I would be willing to hear any compelling case for anything beyond these GPU solutions in terms of price or performance. For me, it is more important that the needs be met than the price be conservative. Although I am not sure I would be adequate myself, in explaining those needs.

Memory: CORSAIR Vengeance LPX 32GB (4x8) SDRAM DDR4 2133

VERSUS CORSAIR DOMINATOR Platinum 16GB (4x4) SDRAM DDR4 2666

The idea here is that the Dominator has a higher frequency at 2666, as well as being the dominator platform, and about $100 cheaper than the Vengeance platform. But the Vengeance platform as a shear doubling of the DRAM and can be overclocked. From reviews involving bench testing (from gaming review/ gaming oriented sites) I saw that the latency/CL and the higher frequency actually cancel each other out(DDR3). Considering my purposes are different than for gaming, would there be a difference in what I would select over a gamer? I also saw from benchmark testing that the 16GB and the 32GB didn't perform much differently, whereas the 64GB made a very big difference(also from DDR3) is there an inherent difference in these aspects when considering DDR4 memory? So on the one hand the dominator is more robust and higher grade, it's clocked at 2666, it's cheaper, it's not that different from 32GB when DDR3; and on the other hand vengence is overclockable which can make up for higher frequency, and it is only 32GB and not 64GB, and it is more expensive. I would also consider anything that was so cheap that money saved for an upgrade in the future could suffice, or any hardware that can best fit the video editing and rendering, and performance in the face of future demands intent of this system.

This is all I have decided for now, thanks for reading. I am off to research some CPU cooling, Fan, storage(including NAS) and case solutions. If there are any suggestons, especially those form fitted to what I have decided so far, such would be greatly appreciated! Thanks againg for your patience and for reading!
