In a perfect world, yes, justice rules supreme for everyone.
In our actual world, if congress overturned the election (which is exactly what it would be), you think the already frothing at the mouth far right wouldn't go apeshit? Imagine if the far right overturned a democraticly elected Democrat. We would lose our shit.
I am all for using every law and policy available to stop fascists. Overturning a seemingly fair election outcome, where the president elect was voted in by electorate AND popular vote is NOT one of those ways.
I think a big question is, what framerate do you want? 30/60/144? Do you also want to run at the highest quality settings?
For reference, I have a 3080 and can 1440 most games at 144hz, settings maxed out. A few new games from this year need some settings turned down, but you mention last gen games, so this shouldn't be an issue.
