Thanks for the info and sorry for the delay, been a bit busy.
My comments are about the build and in now way a criticism of your capabilities.
Blender is the most demanding of your applications, at the moment, and as I see it, you are a enthusiast and not running mission critical production. System requirements, > http://en.wikipedia....re_requirements.
For your future modelling. 3D modelling with Pro software like AutoDesk often use an i5, but a Pro GPU, Quadro. This is where you are making a compromise as you want to play games, hence the upgrade to a GTX 970 for the increased Cuda cores against the GTX 760. ie. > http://usa.autodesk....=8192&system=98
GPU, 760 to 970 > https://developer.nvidia.com/cuda-gpus
XAMPP/WAMPP. I assume you will be using as a local/host and not an actual server. System requirements are minimal. will you Dual Boot Windows/Linux?
I think the LGA2011-3 platform is overkill and the money is best spent elsewhere in the system.
RAM. Stay with 16GB as for many applications more is better, also if you upgrade later, it is no longer a matched kit and no guarantee they are compatible, even from the same manufacturer.
Drives. I consider a 120GB SSD to small. It is not the capacity you end up with as some iss taken by the SSD for management, firmware and over provisioning + OS installation drive partitioning.
250GB SSD, OS/applications.
1 HDD, Data storage, project source files.
1 HDD, scratch/cache, (where software allows) + rendered finished projects.
PSU. The Corsair CX600 is the low end Builder Series and I recommend supporting your other quality parts with something better, one listed comes with a 10 warranty.
MB, recommend the Asrock Extreme6, excellent board just used in my new build.
Case, very nice. I would install another fan as it only comes with 2 pre installed.

Just seen your edit.
A single stick of RAM is dodgy, better with two, if one fails, you still have a working rig.
The cooler will be fine, but add another case fan.
Don't like any TIM that contains electrically conductive materials, seen even experienced builder who have caused shorts.
GPU. cards with 4GB of vRAM will perform much better when rendering and with large or multi monitors.
