Dont use these websites... its telling you to upgrade to a Xeon E5-2608L v3... 6 core 12 thread at 2ghz... this is a CPU from 2014. Just go to the developers website to see what you need to run the game.
To run today's games at all requires at least a new dedicated GPU. Nvidia recently did a driver update so PUBG runs better on Nvidia cards plus CPUs doesn't really play a big part for games but GPUs do.
Here's what you need to run PlayerUnknown's Battlegrounds on your PC, according to developer Bluehole:
OS: 64-bit Windows 7, Windows 8.1, Windows 10
Processor: Intel Core i3-4340 / AMD FX-6300
Memory: 6 GB RAM
Graphics: Nvidia GeForce GTX 660 2GB / AMD Radeon HD 7850 2GB
DirectX: Version 11
Network: Broadband Internet connection
Storage: 30 GB available space
One last thing to add... there will always be bottlenecks in the computer world.
