Yes, I knew your chip had great new GPU technology. The only time I messed with integrated graphics that were worth it was the AMD A series. They had some kind of pairing system with a dedicated GPU. I can't remember what it was called or how to do it, but I paired it with an ATI 2400 firepro and it would run anything. This may be the same for you. All you may need is some low end GPU to pair with it for extra GPU RAM or something else I cannot explain other than my previous experience, that is 100% truth. I know it seems redunculous, but it is true as the grass is green (granted, the grass is watered).
I know your CPU benchmarks at around 9000, on Passmark. I also know people are pairing CPU's with those kind of benchmarks with GTX 1080's. You shouldn't have an issue to get the highest card money can buy. Heck, I know someone with a GTX 1070 and a CPU made in 2006 (the Q6700). Now, we both know that is an extreme bottleneck on the CPU, especially benchmarking around 3400 on Passmark. He has had the GTX 970 for 2 years prior. The CPU is still kicking and hasn't died yet. Sure, it is a good thing to be cautious, but I think you'll be okay no matter which way you choose to go.
I'm not too sure if I am hot or cold to what you want to hear, but those are things I thought of after your reply. I thought you may want to know them.
