lukazzo :
so a game played with a pc + 1050 will run worse than the same game on a ps4? also with almost same fps and quality settings?
Well as already mentioned, it depends on the game. You mentioned DiRT 4 above, so you can forget trying to get that on a PC to look as good and play as smooth as on the PS4 variant with a GTX 1050. I have D4 on both PC and PS4. It's a big time hog on the GPU. Codemasters really screwed that game code/port up compared to DiRT Rally which was way better on frame rates.
But if you play a lot of indie tablet and smart phone type games, they are generally very light on hardware . Many can even be run off a PC's onboard CPU graphics. Again, for AAA FPS, RTS, and racing games, get them on the console unless you can afford more than a GTX 1050 and decent CPU in a PC (meaning minimum of a GTX 1050Ti and Core i5 or Ryzen.
This is all just hardware only advice, and not counting if you are better on a mouse and keyboard for shooters than on a controller (which I am which is why I never buy AAA shooters on the console). Oh and there's one thing to keep in mind that nobody else has brought up: with a PC, online gaming access through the likes of Steam and GOG is free. With a PS4 or XB1, you have to spend $60/yr for an annual membership gaming account - however you get access to free games every month and own them so long as you keep an active membership. I've scored some great deals between the PS3 and PS4 over the years and consider that $5/mo well worth it.
