:lol: your best option is the strongest consumer GPU in existence -- assuming you want a single card solution
Today, you're looking at a TitanXp or 1080TI.
Resolution + Graphics Setting. If you want to max those out, the FPS you get as a result is the "max".
If you want to play any game in existence today, at 8K, Ultra settings, 100's of FPS.... your requirement is a time machine.
