If there is any chance whatsoever that you may decide to overclock your CPU then it makes a lot more sense to go for the 2600K "K" version which, thanks to its unlocked clock multiplier, is a lot easier to overclock. For the few extra pounds it costs, I would recommend taking the K version just on the off chance because there are easily 10%+ performance gains to be had. Otherwise this is still a superb processor and still holds its own against the i7-4770 which is its two generations newer replacement. [Feb '12 CPUPro]

MORE DETAILS

The i5-10400F is a six-core hyperthreaded CPU from Intel’s latest Comet Lake series of desktop processors. This 65 W CPU has single core and all core boost frequencies of 4.3 GHz and 4.0 GHz, respectively. Whilst the 10400F will require a new LGA1200 motherboard, such as the Z490, Intel have guaranteed that the next generation of Rocket Lake CPUs will also be compatible with this chipset. The 10400F is aimed at mid-tier gaming PC builds, and as such, ships with a cooler but without integrated graphics. Despite being officially launched in Q2 of 2020, at the time of writing, the 10400F is still not widely available. Compared to the similarly priced Ryzen 5 3600, the 10400F’s lower memory latency gives it the lead in gaming and effective speed benchmarks. Since the Ryzen architecture creates a gaming bottleneck, it is necessary to upgrade to a higher tier, Intel CPU for better gaming performance. On the other hand comparing the i5-10400F and the i3-10100 shows that the 10100 offers comparable gaming performance for 22% less money whilst also including integrated graphics. [Jun '20 CPUPro]
