Excuse me, what is 3A platform? Do you have 3N?

The 3A platform means that the cpu is AMD, the motherboard chipset is AMD's chipset, and the display chip of the graphics card is ATI (ATI company has been acquired by AMD), so it is called 3A platform because it all starts with A, and 3N platform does not, because NVIDIA does not produce CPU, but mainly produces motherboard chipset and graphics card chip. NVIDIA in brackets indicates that the motherboard is NVIDIA's chipset, nforce980a refers to chipset model, and socket AM3 refers to chipset. It doesn't matter if you don't know the computer, just know how to give it to me!
