Something like that was my plan but, you think its worth to wait for 6th gen cpus?
the CPU's don't really matter much in gaming since welp anything with an intel label slapped on it is good. It's more about the GPU that matters for the gaming part of the "gaming laptop". No matter what type of laptop you are getting, you are going to sacrifice performance FOR portability and size.
That being said, making as little sacrifices as possible is the ideal. I can't guarantee a $1500 laptop will run every game at 60 FPS on high/ultra but It will probably run the more demanding games at Medium settings. Mobile GPUs for Nvidia are getting closer to the performance of the desktop versions, but the gap will always be there.
