dude, i dont want to seem rude but you are way off on this subject. The Pro is a HUGE upgrade. I bought a gtx 1080 but kept the sane processor for my pc. Suddenly my computer was capable of native 4k gaming, running everything on max at well past 60, and ready for VR so saying just adding a gpu ( which has well over twice the processing power) is insignificant is a bit assinine. That is why a high end graphics card is the most expensive part to a gaming PC. The cpu has been modified to run faster and I am sure the talented engineers at sony are not going to wast a bunch of money upgrading the the gpu if they felt like it would just be bottlenecked.
