Dude, don't worry about it, like I said, save your money. If it's not important to you, it's better to keep it that way.

It is important to me, I'm gonna keep doing it.

As we get higher and higher frame rate, there are certainly more and more people that won't care.

But you can't say it doesn't make a difference, in blind testing(name of the testing style, obviously) people who freshly walked into a room with a game running and were asked if it was 60 fps or 120 fps guessed right 100% of the time, literally no errors made, they were not gamers. But they did have one training attempt each of walking in on each setting knowing which one it was that time.

So literally everyone -can- see the difference, but not everyone cares.

It is a real thing anyway, unlike cable quality for digital audio.
