Especially when you take into account the PS4 (not even pro) will play 4K Blu-Rays. You still need to purchase a special 4K player if you want to watch a movie!!!! I only found this out recently.
So yes, I do agree, the base model PS4s are lemons, compared to what the advertising spiel led us all to believe at release. And the Pro is only barely adequate for games and still does not play 4K discs!
And here is an interesting site

The funny thing about this is that maybe GTS/7 (whatever) may not even make it onto a PS4 ;-)
It almost makes me want to go out and buy a gaming PC again ;-) (I thought I would add that before anyone else did) :-)
