I've never really cared about graphics that much, so the power of a system doesn't really matter in my point of view. As long as I can play the games I like that have good storylines and so forth, then I'm happy and pleased. Yes, I grew up with a console (PS then PS2 and PS3) but I also grew up with PCs. Even Grew up with an Atari (2600 I think, don't remember exactly) and I played on it every day together with my siblings (switched player since we couldn't play 2 to 4 people at the same time) until it broke I think. Have played a lot on all the Consoles/PCs I've owned and noticed that nothing can replace one another, in my point of view, cause all have their own system, functionality, mechanics, programing and so on... Sure, you are able to play the game on the computer or console today, but when you were younger and played the game on whatever you played it on, it had flaws that made it a little more difficult. Maybe you couldn't push 3-4 buttons at the same time on the Playstation or maybe your atari couldn't take the rapid button press you do cause you're too fast, maybe you need to make sure you time it right. It was something extra you had to master to be able to be good at it. Looking at it today, you will never have the same problem, the same feeling or whatever other difference there is cause you are playing it on a system that reads the buttons flawlessly and so forth.
Anyway, what I'm saying is that even though the PC is better at specs, the PS4 or XBox might have stuff you'll never have with the PC. I like final fantasy, tomb raider and crashbandicoot, and I remember most of them being created for the Playstation consoles and not the PC (made on a PC but not for the PC, feels a little silly but yeah). PS4 might not be as strong as a PC but it might feel a lot better to use than the PC and it still might have games that you can't play on a PC. I like the PS3 cause the OS just feels awesome to me but I bought it at first cause it was better at specs than my computer and I've always liked sonys controls. Now it's a lot worse than my computer but I still prefer some of its games over the computer and watching movies with it is a little more simple with the controller.
BTW I also love Left 4 dead (1 and 2), Counter strike (all of them), Half Life (all of them), Guild wars, Warcraft 3, Heroes of Newerth, League of Legends and so forth. I'm not just a console lover.
Sometimes I play on my gameboy colour cause I like the button system for pokémon and also so much nostalgia. I also love to play on the PS2 cause I love the console version of Everquest and I also love Resident Evil Outbreak (1 and 2).
PS4 might be worse than a computer, but I might still buy it if the OS pleases me and if the Final Fantasy games are made for it, cause I like those games. I(!) like those games, do you? if not, then maybe it's not for you.
You never know until you've tried it. All are beginners at start. Don't hate cause it's not telling you what you want to hear, just ignore it (don't buy it) and move on.
