Hardware upgrade and optimized setting recommendations

Hey guys
I recently installed the free version of Resolve 15 and I'm extremely keen to get started learning but unfortunately my computer isn't yet fully allowing me.
I have a Lenovo E51-80 laptop with an Intel(R) Core(TM) 15-6200U CPU @2.30GHz 2.40GHz processor, a 64-bit operating system running Windows 10, 8GB DDR Ram, 500GB Solid State Drive and an Intel(R) HD Graphics 520 GPU.
I don't get realtime video playback with this, no matter what setting changes I try to make and the program crashes when I try to generate optimized media.
I intend on upgrading to 16GB RAM. Please advise if this is the next best thing for me to do, what else I can do in terms of optimized settings to be able to edit 4K footage and if it's going to be necessary to upgrade the GPU? I obviously want to move forward as cost-effectively as possible.
Thanks in advance for the advice!
