Yes he is
Yes, but would take a cheaper board
Yes, but could get better for the money
All well, but would rather install a larger SSD, since you quickly used up 250GB.
What are the alternatives?
First, a second hard drive HHD / SSD would still recommend you, because the little memory I quickly full. CS: GO runs on almost every computer and the other games run on Full HD (1080p) with high settings in 60 frames per second.
If you want to play in QHD games, it becomes difficult with the 6GB VRAM.
