In one of the issues on YouTube Serodji, experts have said mistakes often make gamers and users most normal when assembling computers.

Error 1: Not taking into account the assembly of games, video cards must be 40-60% of the entire cost of the computer. For example, if you have a budget of 80,000 rubles, then Ryzen 5600 and RTX 4060 will be an ideal combination. In this case, you need to build based on the requirements of the programs you need.
You should not use the processor for games, with more than 6-8 nuclei and 12-16 threads, corresponding **. With their larger quantity, the potential of the processor will no longer be revealed, if you only play.
Error 2: Buy Intel. From 12400F, you will receive less than FPS in some games compared to Ryzen 5600. For example, the 325 f/s version of 223 f/s.
Error 3: Gather in 1851. If you are a blue supporter, then in this case you do not have a full choice.
Error 4: Take the frequency of RAM on the original product card. Suppose you have Wifi 7500F and MSI B650-S. They have different frequencies. To understand which installation you need to install, see the specifications of the motherboard.
Error 5: Buy cheap AM5. This applies to 8400F, A620 or B650 budget and 16 GB of DDR5 RAM.
