Will Premiere Pro CC 2018 suffice with an Intel i7 8700, GTX 1080 8GB, 32GB RAM config for 4k editing?

I've been editing videos (for Youtube channels) in Premiere Pro CC 2015 on my iMac 5k (base i5 model with a shockingly weak GPU) for over 2 years now. It suffices to say that Premiere's performance on a Mac is pretty disappointing if compared to Final Cut Pro X. My iMac can barely handle 1080p footage in 60fps in Premiere.  So I've been meaning to switch to Windows and build my own video editing machine. iMac Pro is not an option as even the base model starts at a hefty $6100 price in India. I am planning to go with an i7 8700 with MSI GTX 1080 Armor X Edition with at least 32GB of RAM and a Dell Ultrasharp 34 curved monitor. What I want to know is how good will Premiere Pro perform on the aforementioned configuration. I am planning to keep the new system intact for at least next 5 years and will mostly be editing 4k footage for Youtube channels and individual clients. Should I opt for even better hardware or will this one suffice?
