@tyrrael: While I appreciate your point of view, I think saying "most people aren't going to notice a huge difference when playing" is a little presumptuous...especially in this community.
I completely agree with him. Sure, 60 fps is better and it's probably a big part of twitch games like CoD or street fighter but devs make sure those games run at 60 fps on consoles anyway. A solid 30 fps in all other type of games is all I need, especially if they dropped 60 in favor of a better open world, better AI or really impressive visuals.
For me I agree with the notion that for the majority of the gaming community don't notice 30 vs 60 fps and don't see it as a major issue. What matters is if the frame rate is stable, because it really bothers me when the FPS dips. All I want is the consistent stable FPS. And I use to play WoW on a really old laptop at 20 fps, which for me was fine as long as it stayed at 20 fps.
As for the OP, I would suggest the PS4 as well. It sounds like that he wants stability and consistent performance which is what the consoles are there for. Consoles are good because developers can optimize them for the machine. It's a little rocky for the games now, but developers will get used to it as more and more games get made for them. Yeah, PCs can go above and beyond, but as others have said sometimes games are just not made to run that well on PCs because of the lack of optimization due to an infinite number of configurations. I don't think you can go wrong with getting either a PS4 or PC, but for you OP, PS4 might be your best choice for now.
