Without a gpu please help
Overclocking your i5-6600k immediately won't affect it until the GPU is installed. The process focuses on the CPU, regardless of whether you have a separate GPU or not.
When overclocking your CPU, it shouldn't impact your GPU. You can boost the CPU right now and then install the new GPU once it's delivered.
I wouldn't experiment with overclocking until everything was installed. Are your graphics cards onboard or is it an older GPU? It's unlikely anything will go wrong, but the power requirements will change, so I'd avoid any adjustments until the system is finished.
It depends on the stress test. If it's a CPU stress test nothing will change. The only thing that could change when installing a GPU is if it's large and produces a lot of heat, then your CPU temperature might rise by 1-2 degrees, which isn't a major issue.
