You still left out the monitor resolution. Is the monitor included in the $2000 CND budget?
I'd also consider downgrading to an i5-4960k, or a non-k if you don't plan to overclock. Assuming this rig is for gaming, we're still not at a point where we're gaining a whole lot from the hyperthreading the i7 adds. Granted, this specific i7 is also a bit faster, but you can hit that with a light overclock anyway.
I'd direct those funds towards a nicer case, mobo, and maybe a larger SSD, as those 256GB models are starting to fill up quickly with large game collections. That's just my opinion of course.
+1 MarkW's comment. Even if you stick with NVIDIA, a new AMD launch usually is followed by NVIDIA price cuts. There will always be new hardware around the corner, but the R9 300 series is pretty close.
Anyway, I'd do something like the build below for $2000. Most of the parts are the best in their class. Let me know if you want more info. Swap in a new video card if you want, and leaves room in the budget for a nice monitor, mouse, and mechanical keyboard. I'd go for a monitor at least 23", IPS, with 1440p if you can afford it, or go with a 1080p, 144Hz model if you like that look. On the flip-side. 1080p + 60Hz is the safe bet, and you should be able to max that out for years with this rig.
This rig also leaves room for a 2nd GPU in SLI/Crossfire, but I'd probably go with a GTX 980 or R9 290 if I was planning to SLI. (VRAM doesn't stack, so 2 970's is still < 4GB of fast VRAM). The rig also allows for some light overclocking. You can upgrade the fan to a Noctua NH-D14 or Closed Loop Water Cooler if you want to push it a little further.
