Well the 4790k is special in that regard. It is the best processor you can buy for the LGA1150 socket. Laid my eye on it too, my plan was to get the biggest performance boost for the smallest capital expenditure. The 4790k would have been a simple swap in and enjoy an at least 33% faster processor in my case. But instead of splunking 140 for one i got a used workstation with a Xeon E3-1271 (the 2. fastest Xeon without GPU) for 180. It included other parts, which made the upgrade free (if you don't count the work i did) by selling my old CPU+Mobo+GPU. The GPU (RX570) i had was at the same price level on ebay as when i bought it. If you badly wan't to upgrade (from a 4670k the delta is way smaller than from the CPU i had), i'd suggest looking for an E3-1281 or 1271 if you have an dGPU, if you need an iGPU replace the last digit with a 6 https://en.wikipedia.org/wiki/List_of_Intel_Haswell-based_Xeon_microprocessors#Xeon_E3-1245_v3 https://en.wikipedia.org/wiki/List_of_Intel_Haswell-based_Xe... (edit: clarify, add last paragraph and links)

> Well the 4790k is special in that regard. It is the best processor you can buy for the LGA1150 socket Little known fact and even less available, but: The best processor for the LGA1150 socket is not the i7-4790K, but the i7-5775C. Faster IPC, significantly bigger cache and a stronger iGPU, and despite not being called a K cpu it's overclockable. https://www.pc-kombo.com/us/benchmark/games/cpu/compare?ids%5B%5D=Intel+Core+i7-4790K&ids%5B%5D=Intel+Core+i7-5775C https://www.pc-kombo.com/us/benchmark/games/cpu/compare?ids%... shows a comparison with many gaming benchmarks. The Xeon route can be cheaper though, it's a good alternative.

  Well, it has the faster iGPU thats for sure. But if you use it for work it is usually slower: https://openbenchmarking.org/vs/Processor/Intel%20Core%20i7-4790K,Intel%20Core%20i7-5775C https://openbenchmarking.org/vs/Processor/Intel%20Core%20i7-... You can't just swap it out too, you need a mainboard with a 9-Series chipset, which you usually don't if you are running a Haswell.

There are many Z97 boards out there that currently run a Haswell processor, all of them do support this broadwell alternative. > Well, it has the faster iGPU thats for sure. But if you use it for work it is usually slower: The pc-kombo collected benchmarks do not use the integrated graphics, that's all cpu performance with usually a high end gpu. The 5775C not only has a better IPCs, it has 128 MByte eDRAM "L4" cache. That's just cool and helps some applications a lot. That it is slower in some benchmarks is just because of the lower turbo clock. Overclock it and it will always be faster than the 4790K - it likely won't reach the turbo clock of the 4790K, but it just needs to come close, together with the higher IPC that should be enough. Then you have the performance advantages that the gaming benchmarks show and match the performance of the 4790K in the multithreaded application benchmarks. It's just seldom available, but sometimes when searching for used processors like the 4790K the 5775C turns up and can be had for less.

      Sure, there are many availlable, but it adds cost. If you don't want the hassle of swapping mainboards the 4790k is a drop in replacement that gives you 4-4,4GHz out of the box.

        If you have a Z87 board. If you have a Z97 board it already is a drop in replacement. Z97 sold like crazy, it's a common starting point for upgrades right now. Just to make sure that comes across :)
