You're REALLY cherry-picking this aren't you because you very cleverly stopped right after the cost of cards went to 4-figures. I don't know if you're just insulting our intelligence or just don't know any better (probably the former). Not all of us are fooled though because some of us (specifically me) have been building PCs since the 80s. Let's take a look even further back shall we?
GTX 1080 Ti: $699
GTX 980 Ti: $649
GTX 780 Ti: $699
GTX 680: $499
GTX 580: $499
GTX 480: $499
GTX 280: $649
9800 GTX: $299
8800 GTX: $599
7800 GTX: $599
Funny how you managed to avoid showing that $300 jump from the GTX 1080 Ti to the RTX 2080 Ti, eh? Well, hiding the truth doesn't change reality, it just makes you dishonest and then nobody takes your words seriously. I know that I won't because what you just did is a marketing trick which means there's a strong chance that you're a paid shill for nVidia. Even if you're not, I just turned any credibility you ever had to dust.
Not THIS gamer because I've been around for decades as well. It's the young noobs that don't know better.
