Regardless of this, it doesn't change the fact that 4k is not yet a practical resolution for the mainstream PC market
That would be why consoles next year are going 4k. You can play your games on a 1660 Super at 4k if you drop the settings from Ultra. Hell, the 1660 Ti manages 30 fps at ultra.
Any game can kill a GPU - RTX, anyone? I've been playing games at 4k for many years now. Get over yourself and start having fun. You can always drop the resolution to 1080p.
