The glass on the lens doesn't even resolve that much resolution. I doubt it's even physically possible to make a piece of glass that perfect. There is a reason people still buy medium format cameras over full frame, the glass elements can be larger and therefore small imperfections are a smaller fraction of the lens. This is also one reason bigger telescopes are always better. Diffraction also kicks in faster with smaller lenses. Even if your glass was perfect, then diffraction of the iris blurs your image.
TCP is a protocol where all the data is verified when sent. There is extra back and forth communication along with the payload to check that the payload arrived safely. Its great for downloading files when you want to make sure nothing is missing or damaged. UDP is more like a constant data stream where the sender doesn't care if it all gets to you. The advantage is that you send less data overall, useful if you don't care if one frame of a video stream looks weird.
One protocol isn't safer than another, its all about how much bandwidth you have/need. Torrenting over TOR uses up way more bandwidth than needed. Depending on the implementation, TCP can use 50% more bandwidth.
It's worth it if the games you want to play support it. If you play fast paced competitive games it may not be what you need. However, if you play a lot of games with high end graphics then it's almost a must at this point. The RTX 2060 will probably be your cheapest option but I personally would skip that card. It isn't very powerful when it comes to the RTX features. The 30 series has the second gen tensor cores so you should get some better performance. The 40 series also supports frame interpolation but those cards are crazy expensive. IMO: a 3060 would probably be a good option; but the 30 cards are dropping prices fast. See if you can find a second hand card for cheap.
