How is your current pc dying? Some parts might be salvagable, or it might even be fixable. You can still get a new one anyway, but if it's a cheap fix you should do it so you can sell it.
When are you going to buy the parts? New GPUs will be released in the next two weeks.
What's your budget?
Other than that some adjustments:
Swapped the CPU for the highest clocked version just because it's within budget.
You don't need an aftermarket cooler (see #1264).
Cheaper mobo.
8GB RAM should be enough. Should the need arise you can just add more. If you want to go with 16GB from the start there's cheaper than what you picked (e.g. http://pcpartpicker.com/part/corsair-memory-cmk16gx4m2a2400c16 atm).
Faster SSD, again because it's within budget.
GPU is mostly a placeholder since you should wait for the new ones which should be even cheaper. However if you're not waiting the Fury is faster and cheaper than the 980.
I'm not exactly sure what wanted for the case (window? sound dampening?). Aesthetics are always difficult so I'll deal with that later or you just pick a case on your own.
Swapped the PSU for a fully modular one. Both are built by Seasonic on a similar platform and the same price, so that's pretty much the only difference.

Yeah you should definitely test it.
Some explanations though: G-Sync and FreeSync do the same. FreeSync is in theory free, Intel will support it in the future but for now it's just AMD. G-Sync costs you about 100$ more which is the reasons why nVidia does not support it in the public drivers (although the could and did in some notebook drivers), since they're still making money with that.
->FreeSync only works with AMD cards atm
But what do G-Sync and FreeSync do? Well usually when your fps drop below your refresh rate you'd either get horrible stuttering or VSync would hack your framerate in half to keep the fps in sync with the refreshes. -Sync just adjust the refresh rate downwards. Only getting 143fps? 143Hz it is. Nasty drop to 97fps? No problem, let's just use 97Hz while it lasts.
So it's really nice when you can't get as many or more fps than your refresh rate, but does absolutely nothing if you do.
Lightboost is the opposite. It's basically strobing, you can read up on how it works, but that's not important. What it does is it prevents you from seeing the frame change. Monitors spend quite a bit of time changing from one frame to the next, so most of the time there's actually two partial frames on the monitor. They blend into each other, which we percieve as motion blur. Lightboost blocks that out so you only see one frame at a time -> basically no motion blur (think CRT). Now that's great for fast paced games (fps etc.) but it obviously won't really help in RTS or Minesweeper. There's also one downside: If you can't get stable fps at a multiple of your refresh rate (1 is fine, but basically you want to cap at the highest you can keep stable, that's usually either 144 or 288fps, assuming 144Hz) you'll see all the nastiness that the blur would usually mask a bit. You get to experience how truly awful screen tearing and stuttering really are. It wil make your eyes bleed.
tl;dr
FreeSync:
-only works with AMD cards, later Intel (G-Sync for nVidia, but more expensive)
-helps if your fps drop below your refresh rate
Lightboost:
-helps in fast paced games (less motion blur)
-truly awful if your fps drop below your refresh rate.
