Firstly, I presume you meant 7680x4320...unless you have a bloody great big cellphone screen you are playing on....hehehe
SO!
It all depends on your financial situation vs your level of OMG ITS SHINY Syndrome.
You do not mention what you are currently utilising, so I'm going to guess a 30xx? And your current performance.
The only reason anybody NEEDS higher FPS these days, is because they have a high refresh massive monitor. So yeah 7680 is gonna get a bit flickery at low FPS.
To clarify, refresh rates = how many times per milisecond the screen is updated, which is why if you take a handheld video of a monitor with a low refresh rate, it looks like it is flickering because they are out of synch
Finally on that aspect, the other reason for upgrades is tech. So if you have a non RTX card...thats about it really.
Fun Fact: While the much touted "nobody can see faster than 24fps"
fact is indeed true and is what dictates movie theatre playback speeds, games do not work like movies.
Games require a solid 30fps to be visually correct, pleasing and...not janky as all hell. To MAINTAIN 30fps...means what you really need is 60fps. The dips and bounces occuring during heavy screen action or in networked games, extra players doing dumb things on screen.
So while anything over 60+ FPS is a bonus, many people rant about it being smoother. Its not. Unless...you have a very high refresh rate monitor.
So both AMD and nVidia have tech to keep 100hz + monitors happy with lower FPS rates being fed to it. I've completely forgotten the AMD one, but nVidia uses "fast" Vsync which works damn well, alongside some other new tech I havent bothered reading up on recently
SUMMARY:
Do you just want to upgrade because you have OMG ITS SHINY Syndrome Rank V? Or is it because you are experiencing jank currently?
To complete this rather long waffle, history is our greatest tutor. And when it comes to GPU's, the shinest newest little monster is never the best financial option, ever. Not for any reason apart form bragging righst, or having aforementioned Syndrome....the cure of which is to get married btw.
Not a recommended solution, but it does the job.
😛
Much like a new car being driven off the showroom floor and instantly losing 15% resale value, GPU's creep, then crawl, then leap then fall (oooh ama poet and i didnt even knowit!) in price.
So the key to GPU buying is knowing the pivot point in Price
😛erformance. In other words, at what price does the performance gains lessen in percentage?
Quick example, going from a 1650 > 2070 will cost you in South African Rands about R5000 presuming you sell the 1650. You gain 127% performance rating
Moving from the 2070 to a 3070 will cost you a further R2000 only 23% performance gain (so 150% from the 1650)
So if I was upgrading my 1650....the 2070 would be my sweet spot (it's actually the 3060 but whatever, you see my point).
Guessing you own the previous model, the 3080....your performance gain getting the 4080 is 56%, but is bloody well R20 000 which for us South Africans is the same as renting a beach front villa or 1 months salary for most. But thats not the point I dunno if you are the next Sultan of Brunei or a carpet seller.
So the price point, in my opinion, is too much. I'd advise waiting, especially considering Intels ARCS are now very very good and affordable....there will be changes and shakeups very soon.
FINAL FINALLY: All major reviewers, and comparision sites, actually currently recommend the 3080 as the optimal
Price😛erformance over the 4080/4090.
