I have an Intel i5-4440 processor @ 3.1ghz, I was looking at some games under load and noticed the CPU was only at 2ghz/1.7ghz even sometimes in CSGO etc. With EIST disabled in the bios the game ran at the normal voltage and core speed. I recieved something like a 6-8fps boost on ultra in some games even. I still have C states enabled, the EIST just downs the voltage and frequency under different loads.

Is it safe to keep this disabled? Would it effect the life of the processor? I just don't want to create any problems as this is a new processor.

Temps are 31-33c idle and about 49c in csgo and 57-58c in more intensive games such as BF4/PS2 with EIST disabled. About 1-2c less when it is enabled.

It will be fine to disable the EIST. You will be fine.
1) your CPU max. temp =72.72°C http://ark.intel.com/products/75038/intel-core-i5-4440-processor-6m-cache-up-to-3_30-ghz
2) When to enable it, and you play some games, if the CPU do not need full capability of the chip to handle those, so it will run lower frequency. That is the intel EIST ( Enhanced Intel SpeedStep® Technology ). If you enable it the CPu will run in full speed, that is why you get some fps boost.
3) Also we do disable the EIST when we do the ocing.
