Why do you think it'll die so quick?
My last card was a rx 480 and it worked for around 5-6 years.
A 1660 ti is significantly more expensive than a 590.
Also how does a 5600 xt compare to the 1660 ti or the 590?
You reap what you sow. This is what happens when you take away choice from consumers. Even with 88% split going to developers, they can't recoup costs. Meanwhile, Helldivers 2 is a massive hit for Sony thanks in big part to Steam.
