The 8700k should arrive on Friday! I also decided to purchase a motherboard to properly build out the i3-8100 that I bought. I decided to finally resub to Netflix, and I realized that I lack a 4K-capable player in my bedroom apart from my TV's built-in software. So, all it takes is a 7th-generation processor or above (with the Windows 10 Netflix app or Edge), and I had that in the i3-8100. Of course, it's kind of awkward when your CPU costs less than your motherboard. I was tempted to pick up some DDR4-3000 for it given reviews showing benefits of faster memory and its decent price (~$150-160 for 16GB: 2x8GB). However, I'll just steal 16GB from my current desktop. It's DDR4-2666, which isn't the fastest shown in tests, but it seems like Witcher 3 is the only game (that I've seen) that really cares when going higher.
I'm being a bit meticulous when building my 8700k system. The Thermaltake Core X9 is a really big case.... or rather, it's deceptively big compared to what you might expect. Since the case has a window, I'm trying to make sure all of my cables are routed as best as possible, and that takes quite a decent amount of fax extensions... especially since I have fans at the top serving as localized intakes for the video card and CPU. I also picked up a 3-foot SATA cable to handle going to the Blu-ray drive, and now I realized that I never picked up a long extension for the power cable!
