You want my honest opinion? It's faster but I'd only get it if I needed it. The longer you can sit on the RTX 2070 Super the more value you get out of it. Yes it is exciting when new graphics cards launch. Especially this time. Unless you have loads of money anyway I'd think long and hard before upgrading. You have had the card for maybe a year or less. The RTX 2070 Super is a great card and just because something new came along doesn't take that away. And obviously you're not made of money. If you were you'd automatically get 2 RTX 3090's in SLI. Jensen would personally deliver them straight from his oven. Lol. But in all seriousness I know there is a lot of hype I know nvidia is great at marketing. At the end of the day all that matter is that you have a good experience while gaming and at 1440p and even some situations in 4K your current card delivers a great experience. I've had first hand experience with the RTX 2080, 2080 ti, 2080 Super and several others. Even AMD. Although the drivers were a mess when I tried them. I know your card is very similar to the RTX 2080 although it's a bit worse it's less than 10%. For all intents and purposes those cards are pretty much equal. I have not personally tested the RTX 2070 Super but I've saw several reviews and I pretty much know how it stacks up.
If you're worried just don't. If everyone was always worried about their PC going obsolete everyone would always have the latest and greatest technology. The fact is people don't need the latest and greatest unless they are trying to do something that's stupid expensive to do like 1440p 144hz or 4k 60 or even something greater than that. If you're trying to shoot for that then yes you need an RTX 3000 series card and you'll want the RTX 3080 not the RTX 3070. And yes the RTX 3070 can do that kind of gaming now but probably not in a year or 2 when more demanding next generation games are unleashed. Not only that... But let's not forget guys that these are just games we're talking about anyway. Why take it so seriously anyway? If you're playing at 1080p or 1440p 60hz just don't worry about upgrading You're fine for the foreseeable future. Also ray tracing isn't that much better on Ampere from what I can tell. It still sucks. The RTX 3090 is only just so beefed up that it can finally offer ray tracing that can kinda work. If not for DLSS some titles I guarantee would be less than 60 fps at 4K with ray tracing on the RTX 3090 even. I would also say that even the consoles will have an option to turn ray tracing off if the player desires 120 fps. Until the performance hit from ray tracing is virtually 0 by method of dlss or pure native resolution I'm going to have to say it's just not a good thing to have running. Personally I'd rather have the higher performance any day. Besides your GPU is probably very close to what is in the PS5 unless they beef it up some more before release.
So basically unless you're trying to do something that's stupidly expensive to do just don't worry you'll still be able to play your games and new ones for years on that RTX 2070 Super. It's still a super card.
4k 30 or 1440p greater than 60 should be perfectly fine and perfectly playable for years.
