"...The Radeon RX 540X and 560X, however, are beginning to show their age even for budget gamers".
Apparently, Apple doesn't agree with you by putting the RX 560 on their new flagship $3k-$3.5K Macbook pro 15. And that brings be to my second question: What is wrong with the Laptop industry? Let me explain. 99% of the laptops will either be ultrabooks with U (low watt) CPUs or "Gaming" with H series CPU and expensive GPUs! What about all the productive people who actually want to have a strong laptop but don't care about games like myself?? Other than couple of exceptions (Apple Macbook pro 15, Dell XPS, very expensive exceptions I should add), there are no laptops (or very, very, very limited choice) for us!!! And don't tell about the workstations with professional GPUs and $4k prices. I am talking about strong cheap laptops for work with H series CPUs! Does anybody work out there, or am I the only one??
