Definitely maybe. We'll help you decide.

Two and a half long years after the launch of the GeForce GTX 10-series, Nvidia’s next generation of graphics cards is finally here, and the GeForce RTX 2080 and 2080 Ti top our performance charts. But should you upgrade to the GeForce RTX 2080 Ti ($1,200 at Best BuyRemove non-product link or GeForce.com) if you already own a GeForce GTX 1080 Ti? As always, the answer is, “it depends.”
In our performance tests across a suite of various games, the GeForce RTX 2080 Ti Founders Edition outpunched an overclocked PNY GTX 1080 Ti XLR8 by an average of 33 percent, and a whopping 45 percent in Middle-earth: Shadow of War and Rainbow Six Siege. Nvidia’s new flagship cleared 60 frames per second at 4K resolution with graphics options cranked to Ultra settings in every game but Ghost Recon Wildlands, whose top-end settings were designed to utterly melt GPUs. If you ditch anti-aliasing and drop the graphics settings in games down to High—a common visual configuration for pixel-packed 4K monitors—the GeForce RTX 2080 Ti clears 80 fps in all the games in our test suite.
But here’s the thing: Most of the 4K monitors available today top out at 60Hz, a speed that the GTX 1080 Ti still meets across the board if you drop some visual settings down to High in games. Heck, the GTX 1080 achieves or almost achieves 4K/60 with everything cranked to Ultra in many of the games in our testing suite. If you already own a 4K, 60Hz monitor, you won’t see any of the GeForce RTX 2080 Ti’s performance gains, because your display simply won’t be able to keep up with it. The GTX 1080 Ti already pushes it hard enough.
There are some cases where upgrading from a GTX 1080 Ti to the GeForce RTX 2080 Ti can give you a tangibly better experience, however (though I leave it up to you to decide whether investing $1,200 or more in a graphics card for 33 percent more performance is truly worthwhile).

Price When Reviewed:
This summer, the first 4K, 144Hz G-Sync HDR displays, such as the Acer Predator X27, made their debut. They are utterly glorious—fast, pixel-packed, and blazing at a robust 1,000 nits. The GeForce RTX 2080 Ti is the first graphics card capable of pushing well past 4K/60 and feeding these wonderful displays at ultra-fast frame rates. If you’ve already invested in a G-Sync HDR monitor and want the best gaming experience possible, no matter the price, the GeForce RTX 2080 Ti is calling your name. Cheaper—well, “cheaper”—4K, 144Hz G-Sync monitors are coming from Acer later this year for $1,300.
Likewise, if you have a nice 1440p, 144Hz gaming monitor and aren’t happy with how the GTX 1080 Ti is feeding it, the GeForce RTX 2080 Ti could give you better performance. Note, however, that the RTX 2080 Ti’s performance advantage dips slightly at 1440p resolution, where it’s 27.9 percent faster than the GTX 1080 Ti. That’s still a very noticeable boost, though again, I leave it to you to decide whether it’s big enough to invest another $1,200 in your gaming rig. (The GTX 1080 Ti cost $700 at launch.)
The GeForce RTX 2080 Ti could pull ahead even further if Deep Learning Super Sampling (DLSS), an AI-enhanced anti-aliasing technique that delivers visual fidelity similar to temporal anti-aliasing (TAA) but 39 percent faster, takes off with developers. Twenty-five games already pledged support for real-time ray tracing or DLSS, though you won’t find either technology active in any games just yet. The GeForce RTX 2080 and RTX 2080 Ti include dedicated RT and tensor core hardware that enable these cutting-edge features. The GTX 1080 Ti doesn’t.
That said, new gaming technologies have a spotty track record for actually gaining support from developers, especially near-term. The ones we’ve talked to are pumped about ray tracing and DLSS, but we wouldn’t recommend taking the promise of ray tracing and AI-enhanced graphics into account if you’re deciding whether to buy a GeForce RTX 2080 Ti today.

Should you upgrade from a GeForce GTX 1080 Ti to a RTX 2080 Ti?
Bottom line: Only consider upgrading from the GeForce GTX 1080 Ti to the RTX 2080 Ti if you have a high refresh-rate 1440p or 4K monitor. And, uh, a lot of disposable income. If you have a 4K/60 monitor already, sit tight with the GTX 1080 Ti.
