Experienced builder seeking GPU advice – 5090/5080 vs 5070 Ti vs AMD for 1440p mix (Tarkov, Arc, RPGs, scenic titles)

I’ve been building PCs for a very long time. I know what I need for most parts and tend to take my time choosing components for the best balance of performance and thermals.
I get that the RTX 5090 would be amazing, but it’s way too expensive right now (and prices have been inflated). I could grab a 5080, or wait and see if the 5090 drops closer to MSRP again.

That said, I’m also looking at AMD options and more affordable Nvidia cards like the 5070 Ti. I don’t need maxed-out 4K everything, but I do love scenic/open-world games like Crimson Desert (great benchmark for visuals and RT).
Daily drivers: Tarkov, Arc Raiders, WoW, Diablo 2/4, Battlefield. I also play lots of modern narrative/RPGs that lean heavily into ray/path tracing.

I have most of the build figured out — just need help matching a GPU to my case/thermal setup. Gaming is a hobby, so I’m flexible and don’t mind spending a bit more for future-proofing.
