My I5 12600K is almost here. A big jump from 10y old AMD-FX-X4-4100 (2core/4thread). 😇

I choose the i5 12600k. It's a bit more futureproof with DDR5 and PCIe5.0 and I don't like to buy new PCs that often. My old one is 10 years old now with an i5-2500k :D So the i5 12600k ideally lasts another 10 years. Either way, it is also about 50€ cheaper than the Ryzen 7 5800X, at least in Germany at this date. I Gotta spend more on the motherboard then, but I think it will be worth it.

Go for B660 motherboard especially Gigabyte B660M DS3H DDR4 and you will just spend fair amount, don't go for the Z690 yet.

On Newegg, the 12600k is at $299.99 currently. The Ryzen 7 5800x usually sells at $386.99 on Newegg but currently has a black Friday sale right now but will probably return to the regular price after black Friday. In my opinion, I would go with the 5800x because of its competitive performance and less power usage than an Intel CPU. Decent Intel motherboards are pricey but the new Z690 motherboards are better than the majority of X570 or B550 motherboards.
