The 1080 Ti is actually quite a bit faster than RTX 2070 or 5700 XT, those are comparable to 1080 but not the Ti.
It's 12% faster which I consider comparable. Anything under 5% I consider identical and anything over 20% I consider to be a different tier. That's what I meant by comparable. Now, if you want to talk
identical, then the GTX 1080 Ti's performance is identical to the RX 6600 XT.
Those cards are newer and slightly more expensive too. 1080 Ti is by far the best bang for the buck, thought if one wants longevity, he shouldn't go with 1080 Ti at this point.
I disagree. I would say that, for longevity, I would take a GTX 1080 Ti over an RX 6600 XT simply because the performance is the same but the 1080 Ti has 11GB of VRAM instead of 8. When it comes to video card longevity, VRAM is life. As for features, there isn't really much difference:
Ray-Tracing:
GTX 1080 Ti - Completely Incapable
RX 6600 XT - Functionally Incapable (As weak as an RTX 2060, so not worth bothering with)
Upscaling Tech:
GTX 1080 Ti - FSR2
RX 6600 XT - FSR2 (possibly FSR3 in the future)
The only ways that the RX 6600 XT really beats the GTX 1080 Ti are power efficiency, driver support, DX12 Ultimate support and the fact that you can buy them new with a warranty. I would personally take the extra 3GB of VRAM over those things because the GTX 1080 Ti has had no functionality issues stemming from it's DX12 version support. I still have some video cards that are over ten years old and still work perfectly. All of the cards in the following pictures are still 100% functional:
2 × XFX Radeon HD 4780 1GB (Circa 2008):
PNY GeForce 8400 GS PCI Verto 256MB & Palit GeForce 8500 GT 1GB Super+ (both circa 2007), XFX Radeon HD 5450 & 6450 (2010 & 2011, respectively) are all at the bottom of this pic:
I also have in storage:
Dell Radeon HD 5870 OEM 1GB (circa 2010) with that weird Dell Handle at the end:
Gigabyte Radeon HD 7970 Windforce 3X 3GB (circa 2012)
If properly taken care of, it is very rare for a video card to actually die.
