That PCPP build has a discreet GPU
Does "Link to my build besides the 980" mean "This build is same as mine except I didn't get the 980 ?"
1. Wish I caught you before you ordered as an Z170 based system, with a iGPU, would be faster than the 5820k
2. Z170 is faster in gaming than X99 with up to 2 GFX cards, you generraly don't wanna move to X99 unless you had 3 cards (3820k) planned or 4 cards (5830k).
3. Of course if you are doing workstation apps on your box, then the 5820k makes sense. Your choices:
a) buy a cheap card to use temporarily.
b) Wait for the DDR5 cards 10xx cards (1070) to arrive; wait fort he DDR5X (1080) cards or wait a bit more fro the non-reference ones to arrive.
c) Wait for the HBM2 cards to arrive sometime in late autumn
