2015 Nvidia GTX 970 is such a piece of shit card, no you couldn’t do modern gaming. It has relatively few pipelines, low bandwidth and has no frame generation capability to make anything new playable.
Especially since in 2015 that likely still meant FullHD in SDR, while in 2025 high end would be UHD-1 with HDR.
They have had to replace the fans on the graphics card a few times and a repaste but other than that they are chugging away.
Also solid lol on "frame generation". Marketing fluff/features like that only exists but because they have run out of real generational performance gains to sell cards with.
