Looking for a game and development computer

[DemSec]

Suggestions on my build?
1080p 120hz monitor or 1440p?
I have read that 1440p monitors don't have 120hz capability and if they do they are overpriced. I am mostly going to be gaming, 3D modeling, and programming. I am interested in doing computer vision as well, not sure if that matters for requirements. Game will mostly be The Elder Scrolls series(including ES 6 which I hope comes out soon), Fallout 3, New Vegas, and 4, Call of Duty, Battlefield, Titanfall so mostly open world games and FPSs. On the development side I am most likely am going to be using Cinema 4D or Maya, Eclipse IDE for android and several other IDE's for C programming, etc. I haven't purchased any parts yet but so far, this is my list:
Motherboard: MSI Z87 GD-65
CPU: intel i7-4770k
Graphics Card: Nvidia Geforce GTX 780ti
RAM: Any 16GB 1600
SSD: Samsung EVO 500GB
HDD: Any generic 2TB
My budget is anywhere from $2000 to $4000, big gap I know.
For cooling, case, PSU I still have no idea what I want/need but for sure a mid tower because of space constraints. I am also hoping this build will last me for at LEAST 4 years. I also read that for research and professional development that the titan black was the way to go but also that the 780ti is better for gaming. I looked at the specs for the titan black and it is lacking in gaming performance in comparision with the 780ti. Any suggestions and insights would be greatly appreciated. Thank you in advance.

Problem: Game development/3D modelling is opposite type of 'rendering' then to 'gaming' and much more expensive investment (easily can top 10K if your not careful). Realistically there is no 'both solution' as you have to give up performance (rendering times OR Frames Per Second) depending which way you go. As you picked a 'gamer's card' you would then when in Cinema 4D, Maya, etc. be quite annoyed if not pissed at how long it took to render "with a 780ti" as you think it should handle it much faster (say instead of a hour to render 10sec of video). But if you went with a Workstation Video card like the Quadro line, then you be getting things done fast for your Game/Video Developement, but reversely you get much 'lower' FPS (say your getting 120fps with the 780 now your getting 50-60FPS with the Quadro) because the Workstation is developed for rendering of video and code development.

Second Problem: 16GB 1600 RAM is NOTHING for Video/Renderings. You will easily max this out and cost more hours to develop then would be necessary. More RAM is always better. Normal Workstations (forum search Workstation and you will find a few builds to compare against here) usually are 32GB, most want 64GB and are buying the higher end Mobos to go 128GB up to 256GB to radically cut down the time and maximize multi tasking (i.e. running Maya, Eclipse AND Cinema 4d on 3 or more screens at the same time 'as a normal workday').

Again I would suggest forum search for Workstation and you will see some other builds to compare to and the notes about why each is more important. Otherwise as a gamer's rig that is quite the kick ass, though the 8xx line was just released by NVidia too.
