I mean yeah, that's my point. We're squirrels. Why the fuck would any intelligent species with the technology to reach us bother making contact with us? You tried to talk to squirrels? Spoiler alert. They're kind of dumb compared to us. As are we compared to "them". If that were to happen, which is statistically insanely unlikely, we're lucky if they just give us a fly-by laugh.
"Look at these idiots stuck on their planet, barely able to send duct tape projects to their one moon."
You ever sprayed an ant hill in your yard? I fully expect any species with the kind of tech to reach us sees us the same way we see ants. And to your point, we would probably treat them the same way we're we to be the instigators. But we're nowhere near that today.
Going back through your specs...bro a 4090 costs basically the same as my whole PC that's running games at 120 FPS+ on a 4k monitor with no issues.
Check out combo deals on Newegg for Mobo+RAM+CPU, or Microcenter if you have one nearby (I don't). Your biggest factor for gaming will be the GPU. You can run 60+ FPS on a 1080P monitor on 5 year old midrange GPUs. If you need 4k res, ask on PCPartPicker forums.
