Is any GPU compatible with any CPU?

Yes, it is compatible. Any cpu is compatible with any gpu. As long as the motherboard has a PCI-E slot (preferably 2.0 or 3.0, but 1.0 is fine) and your power supply can output enough power, you’re fine.

Does any graphics card work with any motherboard?

No. You can’t just put any graphics card in any motherboard because the motherboard has to be compatible with the graphics card. You see, graphics card are getting more and more powerful which requires the graphics card to have a better and more secure connection with the motherboard.

What is PCIe 4.0 x16?

PCIe 4.0 is the fourth generation of the Peripheral Component Interconnect Express (PCIe) motherboard interface and will double the bandwidth available to graphics cards, hard drives, SSDs, Wi-Fi, and Ethernet cards. Gigabyte also teased that it will release a new PCIe 4.0 SSD at Computex 2019.

Does PCIe 4.0 matter for gaming?

PCIe 4.0 storage drives are generally not worth the money as they come at a premium compared to current generation PCIe 3.0 drives (which can still be extremely fast), and in most situations you’re better off investing your money into more impactful components like your CPU, RAM, or graphics card if gaming.

What does PCIe 4.0 do for gaming?

Looking into the future, you can expect that increased bandwidth will become more important, as the best gaming monitors usher in high refresh rate 4K resolutions as the new standard. PCIe 4.0 and its successor should boost fps even more when 8K resolutions roll around, as it’ll be far more bandwidth hungry.

Are PCIe 4.0 SSDs worth it?

Usually if you have to ask this question, it is not worth it. The PCIe 4.0 Bandwidth is pretty much only relavent for very fast SSDs or arrays of SSDs doing very heavy i/o workloads. So if you aren’t sure why it would beneficial for you, you probably are not doing anything that can utilize it.
