Back in the day it was still faster than a 12900k in gaming, and only make sense for those who have a zen 2 or even zen 1 CPU to do in socket upgrade, getting a b660 and 12700f you will need either fast DDR5 or getting slower DDR4 to boot, not to say needing to reinstall everything for a new platform. For a completely new build in 2022, the general consene was either go with Alder lake which have 1 more generation and saw significant improvement over 11th gen, or go for AM5, and the reviews back then IIRC also says something similar, not going for the dead platform at full cost, buying brand new, nobody ever said it was a bargain for gaming performance, just reasonable if you want to final extend your platform 4+ years old platform.Im not talking about 2024, im talking about 2022. For the whole of 2022 the 5800x 3d alone cost more than a b660 + a 12700f combo.

Overall, I really like what AMD has done with the Ryzen 7 5800X3D. The technology is impressive. The problem is that the processor is quite expensive. According to AMD, it will sell for $450, which is $100 higher than the Ryzen 7 5800X that is already a highly capable gaming machine, and a better choice for gaming than the 5900X due to its single CCD design. Strong competition comes from Intel's Core i7-12700K ($385), and even the i5-12600K will offer good gaming performance for $260. On the other hand, if you're only looking for gaming performance and have been eyeing the Core i9-12900K ($600) or 12900KS ($750), the 5800X3D is definitely worth considering. Its gaming performance is "close enough," and its lower application performance won't make any difference for most gamers. A huge benefit over Intel's Alder Lake offerings is that the Ryzen 7 5800X3D is drop-in compatible with virtually any AM4 motherboard. This means you can continue using the motherboard and DDR4 memory you already have. Reinstalling Windows isn't necessary, either—it's fire and forget. AMD's next generation of Zen 4 processors releases this year, with DDR5 and PCI-Express 5.0—no doubt, it'll be an expensive platform at first, too, just like Intel's 12th generation. Considering that, the Ryzen 7 5800X3D launched fairly late in the game, but that gives it the potential to become a final option for current owners of an AM4 Ryzen setup to hold out just a bit longer with one final upgrade, and its price may drop into the sub-$400 region by then.
