Skylake is also 2 channel. The maximum memory bandwidth on an i7 6700k is 34.1GB/s, DDR4-3200 is only capable of 25.6GB/s.
Unless you can use more than two thirds of the bandwidth the processor is capable of handling, you can't achieve this with most tasks to begin with. Things like video encoding, compiling. You can handily outperform the Skylake architecture with different architectures on certain tasks because of that limitation, but it's a very select few tasks for the typical gamer. If AMD is concerned with competing against Skylake, a high bandwidth application isn't going to matter much even in the rare instances where it would matter.
For the most part this is true until you take into account virtual memory. Windows does this. In order to keep things from crashing all your memory has to run at the same speed. Unless you have an ssd your virtual memory slows down the system.
Admiral, I will likely have 32 gigs of DDR4 Quad channel and an M.2 SSD like the Samsung 860.
This is only true when a program is utilizing that virtual memory alongside your RAM. If it is, you have massively less RAM than you need. Buy enough RAM that you never need virtual memory, or go back to the 90's where your computer belongs. 
SSD's aren't fast either, so little to no help there. Assuming you meant the 960, the pro is still only 3500MB/s sequential read, as opposed to the above stated 25.6GB/s. They may be an order of magnitude faster than disk drives, but they're still an order of magnitude slower than RAM. If your processor is every trying to work off the drive, it's going to have performance more in line with your phone than a modern desktop.
