I had a similar problem once when I incorrectly wired my PSU to my GPU. I didn’t realize that if the GPU has two PSU inputs, it requires two separate lines rather than a single line split. Seems obvious, but I’m not very bright.
Anyway, running two separate lines to the GPU fixed the problem.
You’re missing the point.
There are a lot of games that look much better AND run much better.
It’s not about how often you upgrade.
