I've ask my youngest daughter if she wants a gaming Laptop or a gaming PC, and she wants a gaming PC.)
I've decided to give my old gaming Rig to her. (i will post it also here named My Old Gaming PC 2017) and build this one as a replacement. I've decided to go RGB with my new setup and SLI GPUs.
With this build, i've no longer planning to upgrade or build a new one for 5 to 7 years :) but if the 2080 ti's hybrid price drops, i might reconsider upgrading.
