Is upgrading from an RTX 4070 Ti to a used RTX 4080 Super worth the cost?

I'm in South Korea and mainly play AAA and competitive games at 1440p on a 280Hz OLED monitor. My current RTX 4070 Ti has 12GB of VRAM, and I'm starting to notice limitations in newer games, especially with path tracing and maximum settings.
A new RTX 5070 Ti currently costs around 1,900,000 won (about $1,400), and I expect GPU prices to rise over the next couple of years. I'm also hoping to buy a future high-end card around 2028, so I'm looking for something that can handle 1440p gaming with very high settings and high refresh rates until then.
I found a used RTX 4080 Super for 1,500,000 won with warranty coverage remaining until late 2027. I expect to sell my RTX 4070 Ti for roughly 700,000–800,000 won after the holiday season, making the upgrade cost about 700,000 won net. The 4080 Super would give me roughly 20–30% more performance and 4GB more VRAM.
Is that net cost reasonable for my use case, or would I be better off keeping the 4070 Ti, lowering or disabling path tracing, or looking for another option such as a Radeon 9070 XT? I'm worried that prices may rise soon and that I'm letting short-term anxiety push me into an unnecessary purchase.

A 700,000-won upgrade cost is fairly defensible in a market where GPUs are unusually expensive, especially if you can sell the 4070 Ti for the higher end of your estimate. The 4080 Super should age better because of its 16GB of VRAM. Just verify the warranty is transferable, test the card thoroughly, and confirm there are no signs of excessive heat, coil whine, or mining wear before completing the deal.

If your 4070 Ti still performs acceptably, waiting is also reasonable. The 4080 Super is faster, but it is not a dramatic generational leap, and path tracing can still require upscaling and frame generation at 1440p. Buying solely because prices might rise is risky; buy only if the current card is already preventing you from enjoying the games you play.

Turning off path tracing would be the cheapest solution, but that depends on how important the feature is to you. If you’ve decided that you want path tracing and high refresh rates, a card with 16GB of VRAM is a more comfortable fit than the 4070 Ti’s 12GB. A Radeon alternative may offer strong raster performance, but it may not match Nvidia as well for path tracing, upscaling, or frame generation.

The 4080 Super is a sensible upgrade if path tracing and maximum settings are non-negotiable. The extra VRAM is useful, and there isn’t much of a practical upgrade between the 4070 Ti and 4080 Super for this particular goal. With warranty coverage through 2027, the used-card risk is lower than usual. That said, a 20–30% performance increase is noticeable but not transformative, so the price only makes sense if you genuinely need the extra headroom now.

MellowOrbit47: The remaining warranty is the main reason I’m considering this particular card. If the warranty checks out and the card passes testing, I’m more comfortable accepting the used-market risk.
