The i3-9350KF is a 9th generation quad core Coffee Lake CPU which is designed to be used with a discrete graphics card. It has base/boost turbo frequencies of 4.0/4.6 GHz. The 9350KF generates less heat than its higher core "K" counterparts so getting a decent overclock without expensive cooling is relatively straightforward. Overclocking the 9350KF to 5 GHz with a $20 USD Gammaxx 400 cooler puts the 9350KF at similar single, dual and quad core performance levels as the 9600K, 9700K and 9900K SKUs. Consequently there is not much difference in fps between the 9350KF and any other CPU regardless of core count. At $180 USD the 9350KF sits amongst the top value gaming and desktop CPUs currently available. Comparing the 4 thread 9350KF to AMD’s twice as expensive 16 thread Ryzen 3700X shows that the 9350KF wins hands down in all five of today’s most popular games. The only other CPUs worth considering for unbeatable gaming performance are the 9600K or 9600KF which have 50% more, equally fast cores, for less than 10% more money.  [Nov '19 CPUPro]

From the point of view of a consumer that typically uses a PC for surfing the web, checking email, listening to music and watching videos, I consider that the Haswell i3 processors currently represent the best value for money. The i3-4130 has a performance profile that is just 7% below the top nine group leader average yet it only costs half as much. Power users that play intensive 3d games or run video editing, graphics design or CAD packages will benefit from more than two cores and will do well to look elsewhere but for regular users overall responsiveness will remain largely unchanged regardless of how much more is spent on the CPU. (My new value pick is the G3420 which supersedes my recommendation of the i3-4130.) [Sep '13 CPUPro]
