10 years ago, $650 would buy you a top-of-the-line gaming GPU (GeForce GTX 980 Ti). Nowadays, $650 might get you a mid-range RX 9070 XT if you miraculously find one near MSRP.
Keeping with inflation (650 to 880) it’d get you a 5070TI.
I don't know how you can consider a 9070 XT a midrange card, it is AMD's second best card in benchmarks and only came out 5 months ago.
$650 of 2015 USD is around $875 of 2025 USD fwiw
That is $880 dollars in today's term. And 2015 Apple was already shipping a 16nm SoC. The GeForce GTX 980 Ti was still on 28nm. Two generation Node behind.
