really my rule of thumb has always been when it’s a significant upgrade.
for a long time i didn’t really upgrade until it was a 4x increase over my old. certain exceptions were occasionally made. nowadays i’m a bit more opportunistic in my upgrades. but i still seek out ‘meaningful’ upgrades. upgrades that are a decent jump over the old. typically 50% improvement in performance, or upgrades i can get for really cheap.
4x…? Even in older cards that’s more than a decade between cards.
A 4080 is only 2.5x as powerful as a 1080ti, those are 5 years apart.
What’s wrong with upgrading once every 5-10 years? Not everyone plays the latest games on 4k Ultra
Admittedly 4x is a bit steep, more like 3-4x
Starfield requires a minimum 1070ti to play. It’s not just about fidelity, you just wouldn’t be able to play any newer games.
