my current GPU is a Radeon RX 480, which i've had for the past few years and i love it, it could run any game i bought on ultra settings no problems, but it's finally starting to show it's age a bit, when i play games like Assassin's Creed Odyssey i can play on Ultra but i get frame dips, or when i'm playing Division 2 i can run it on Ultra, but according to Task Manager it runs my GPU up to 96% so i end up playing on Medium, anyway, the TL;DR of it is at whatever point i decide to upgrade, what should i look for besides the VRAM of a card? what other specs are there to look at and what do they mean? now i'm not expecting someone to tech me all about GPUs in this forum (though that would be very kind) but if someone could link me to a good article where i could learn more i'd appreciate it, just so when i finally decide to upgrade i can make the best decision.
