I just built a new PC (
https://pcpartpicker.com/list/) and sprung for the I7-8700K-based system. I was moving from a i7-2600 and I really wanted to go with AMD this time, but the 2700X still seemed too far behind the i7-8700K in gaming. I'll be gaming more than performing productivity-based work, so I justified the cost in that regard for gaming. Also, I scored the i7-8700K, Gigabyte Aorus Gaming 7 Z370 mobo, and the G.Skill Trident Z RGB RAM in a combo getting a $45 discount on top of sale pricing and rebates, so I think the "extra" was worth the cost of admission.
Now, it's just waiting for the GPU pricing to come down. I'm still debating the possibility of just buying a 1060 now and then picking up a new 1180 when they arrive. Although, there are some decent 1080 Ti deal right now, I'm hesitant to pull the trigger when the 11xx series is just around the corner.
Thoughts?
