The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]

The Intel G4560 is one of the first Pentium processors to feature Hyper-threading. This means that although the G4560 only has two physical processing cores, it is able to process four threads in parallel by sharing resources between the physical cores. This typically results in a 50% performance improvement over two physical cores alone. Comparing performance between the lowest spec Kaby Lake i3 7100 and the Pentium G4560 shows that in terms of both performance and specs, very little separates them (even virtualization technology VT-d is present on the Pentium). The Pentium does lack AVX 2.0 (Advanced Vector Instructions) and it trails the i3 7100 by 400 MHz (10%) but there is no longer a clear divide between Pentiums and Core i3s. Intel have achieved an almost continuous distribution of performance levels for each price point from the cheapest Pentium to the top end i7-7700K[Jan '17 CPUPro]
