The i3-2120 is a very old CPU at this point. Whilst capable of simple tasks like web browsing and videos the weight of ageing has hit it hard with newer software running more slowly. With only 2 cores it doesn't handle multitasking very well and is also an extremely poor choice for more modern gaming. Though if you're not doing anything but light usage it's okay, but you can almost definitely find something better for the same price. [Jun '19 Robotonic]

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
