I've got a 1080 Ti from a few years back and I'm struggling to hold 60fps at 1440p with recent titles like Dragon Age: The Veilguard or Indiana Jones. Is it worth getting a 5080 or should I wait a bit longer? Anyway, the rest of my PC is solid - Ryzen 7 5800X and 32GB of RAM.
Don't make the mistake of thinking a 5080 is automatically the right choice just because your current games are running poorly. The 1080 Ti is still a decent card, the problem is that today's titles are simply more demanding and that generation is starting to show its age. With a 5080 you'd get a nice performance jump, but you need to ask yourself if current prices make sense for you and whether your monitor can actually take advantage of what it costs.
Honestly, the rest of your PC is solid - the 5800X still holds up really well, your RAM is more than enough. If you love those specific games and want to play at high settings in 1440p at a stable 60fps, the upgrade makes sense. The 5080 will run them without a sweat, but it comes down to how much you're willing to spend and whether you're really willing to wait. If you wait a couple of months maybe other options pop up in a lower price range that still do the job, or current prices drop a bit. In general, if you can afford the 5080 without breaking the bank, it's not a stupid upgrade - that card will last you years like the 1080 Ti has lasted you.
The 1080 Ti is still a solid card, but current games are way more demanding and at that resolution and frame rate you'd want something more recent. With the rest of your PC, you'd really get good use out of a 5080 and you should be good for the next few years.
How much budget do you have and how long can you wait? With a 1080 Ti and those heavy titles at 1440p, yeah, the upgrade is justified - the rest of your PC is solid and won't hold you back. A 5080 would be overkill if you're only gaming at 1440p, honestly a 5070 Ti or even less would already give you what you need, but it depends on how much futureproofing you want. If you've got the money now and don't want to wait another few months, go for it; but if you can get by with lower settings for a bit, maybe in December prices will drop or other options will come out.
With that setup, the GPU is definitely the bottleneck, so the upgrade makes sense. The 5080 would give you a solid performance jump over the 1080 Ti - we're talking roughly double the raw power - and with 1440p and stable 60fps on heavy titles you wouldn't have issues anymore. The only thing is the price is pretty steep, so if your budget isn't huge maybe consider whether a slightly less powerful option (like a 4080 if you can still find one) would solve things without emptying your wallet. Either way, your Ryzen 7 handles basically anything you throw at it just fine, so you don't need to worry about that.
A 1080 Ti handles 1080p games pretty well today, but at 1440p with titles like these two it's really hitting the ceiling - it's not a matter of "it's still decent", it's that the architecture is ten years old and modern drivers don't optimize much anymore for Ampere cards and older. A 5080 would actually give you a huge boost, but the problem is that in 2026 the market is in a weird spot: new generations keep dropping and prices keep swinging.
If you're in a hurry to play now, the 5080 is a solid buy - your processor and RAM won't hold you back at all, so you won't get any surprises. What I'd suggest though is waiting even just two or three weeks to see how prices settle after the latest GPU launches, because there are often price corrections and unexpected deals. In the meantime you could dial down the graphics settings a bit (medium textures, limited ray tracing) and get by that way - it's not the best visually, but at least you'll hit 60fps.
The other answers are right that it's a sensible upgrade, but nobody mentioned one thing: a 5070 could be the sweet spot for your situation. It'd cost less, still give you three times the power of your 1080 Ti, and honestly at 1440p with 60fps as your target you shouldn't need to go all the way to the top tier. First, try to find specific benchmarks for these two games with the 5070 - if it hits 60fps at high settings without breaking a sweat, save yourself the money.
How much do you usually spend on games per month? Because yeah, the 5080 would give you a nice boost, but keep in mind that drivers and game optimizations evolve too - sometimes waiting 3-4 months makes a difference without spending anything. The real mistake nobody mentioned is that a 1080 Ti sometimes performs better with older drivers, so before you jump into a new card try rolling back your Nvidia drivers or make sure you're using the right settings in your games 🎮
