I have a I5 2500K that cant be overclocked because theres no motherboards with the needed chipset in my country's market, so Im thinking about an upgrade but I have no idea on how to estimate how better will the new processors to perform compared with my current one. Its impossible to find benchmarks with both the 2500K and the newer ones.

thanks

Your only real upgrade path is to a Intel Core i7-3770 or Core i5-3570

Core i7-3770

Having said that I would feel bad recommending a $200-400 cpu that came out 5 years ago.

You won't see the speed increase you would like switching from one series to the next unless you also went to the i7 version which may be a noticeable speed up if you are running multi-threaded applications.

You can't go passed the 3xxx series due to a change of cpu socket.

1155 to 1150 to 1151
^Yours ^4xxx -- ^6xxx and 7xxx

After buying a new motherboard, ddr4 ram and a new cpu you might as well just buy a new computer, which is effectively what this "upgrade" would be.

Each generation of Intel processor since your Sandy Bridge has been roughly about 5% faster at the same clock, so the current Kaby Lake is about 28% faster. That slow progress is what everyone has been complaining about for the last decade but there's nothing that can be done as long as AMD is not competitive.

To put this into perspective, you can agree the jump from Pentium 4 in 2005 to Core 2 in 2006 was a huge leap, right? Well according to the Sunspider benchmark of Java, Core 2 is roughly 3x faster than P4. At the rate Intel has been improving, they won't have a chip 3x faster than Core 2 until 10nm Icelake shows up in 2018, or 12 years later.

Of course it depends on the application, and two specific types benefit from memory bandwidth improvements--the previously mentioned games and compression utilities like Winzip. I expect for the home Office user a Pentium 4 is still perfectly usable today even though such a machine would be nearly unusable for web surfing.
