It is worth it, but only for a short time. once you get used to it, it won't feel any different, because that's exactly what people say for upgrading from 1080p to 1440p, and from 1440p to 4k. Once you upgrade, you'll never want to go below back and everything below that will feel jaggy and horrible. 1080p is the today's standard, though. According to a Steam survey 98% of gamers use 1080p panels. That means they're very cheap and I say it's worth it (if your hardware can handle it, of course).
