The OP's setup is absolutely great. Encore.
I recently got a new PC for rendering - these are da specs.
CPU
Intel Core i7 'Skylake' 6700 @ 3.4 GHz
GPU
NVIDIA GeForce GTX 970 - 4096 MB GDDR5 RAM
RAM
16 GB Dual Channel DDR4 RAM
Yep, those are the main things - I could safely say I probably have the fastest computer in approximately 20 kilometres.
Now, I'm a renderer, and when you're a renderer, your CPU is to your GPU as your VW is to a Lamborghini - in other words, my GPU renders approximately 6 times faster than my CPU. I happened to get the optimal GPU for rendering, and my computer starts up in approx. 6 seconds, so I'm happy.
P.S. Try CPU-Z (free!)
here - it gives a big long list of all your system information, right there for you to brag about.
