The i5-10600KF is a great processor, but to unlock its true potential you need a Z series motherboard to overclock it. Otherwise, I don't see any reason to pick it up over something like the 5600X from AMD or i5-12400 from Intel, both are ~200-230$ right now. They are going to be slightly more expensive than the 10600KF, but you get the benefit of great performance out of the box, and access to more modern platform with PCIe4 support for both.
The Ryzen 5600 is also releasing soon in April for 200$ MSRP, it also should be better than the 10600KF at stock settings, it will retain the same cache of the 5600X, so performance will be similar and you will get the same benefits of a better platform with PCIe4 support.
B550 mobos for Ryzen CPUs are not expensive, and something like the 5600 or the 5600X will be easy to cool and operate even with 100-120$ motherboard.
This board from Gigabyte isn't the best B550, but its more than capable of handling a CPU like the 5600X or 5600 with no issues, and its inexpensive. With PCIe4 support, it has 2 slots for SSD so you can install 512GB part now, and add 512GB/1TB Gen 4 SSD in the future if you ever wanted to do that.
Also, you can get a GPU like the Radeon's RX 6600 which is faster than RTX 2060 and cheaper on Amazon. The RX 6600 has only 8-lanes so PCIe3 bandwidth does affect its performance but even then in this case its faster than RTX 2060, and has 8GB of VRAM instead of 6GB. But on a PCIe4 system, its much faster than 2060, its as fast as RTX 3060 here, and much cheaper.
No reason to not get a faster memory,
this RAM on Amazon has the same price of the one you mentioned, and it has 3200mhz XMP out of the box.
If you want to go Intel route,
this board is also inexpensive and should be capable of handling the 12400 just fine. Even with 65W power limit, the 12400 is slightly faster than a 10700k out of the box, though according to
this review, the 5600X is faster than both. the Ryzen 5600 coming soon next month should be at the same level of i5-12400.
As for the PSU, the
650W unit is a couple of bucks more expensive, and it can prove beneficial in case you decided to upgrade the GPU in the future : )
Such build is going to be just slightly more expensive than what you are targeting (unless prices are very different where you live), but the GPU is actually cheaper so it will even out, and you will end up with a more modern and flexible system. A GPU upgrade alone with the same parts, like RTX 5060 or something similar down the line, will be even capable of handling 4k/1440p resolution without the need of changing any other part in the computer.
