Spend more on GPU than on the case and keyboard if you want to call it high end gaming.
IMHO Superhigh-end gaming should be more like dual 970's and a 4K display, 3 x 1080P, or 2 x 1440P.
Save $100 each from the motherboard, case, and keyboard - use it to get a second 970. Though you might need to add some $ for a bigger PSU if OC-ing the CPU and dual GPU.
