The 2012 series came with three options 2.7 or 2.9 GHz (Core i5) or 3.1 GHz (Core i7)
Depending on your applications a single threaded app won't see much improvement, a multi-threaded app will see the most! As you can compare here:
To get a better idea if its worth it for your workflow review your apps to see which ones are multithreaded, then figure out what actions you perform that consumes the most time. Then you should be able to extrapolate if given the needed work, costs and risks of damage is worth the effort. As an example is 10 minutes of time waiting for an image to convert from one file type to another going to benefit you? One or two files likely not, hundreds for sure!
I'm a photographer so my needs are a bit different from a game developer,
But I'm sure this is not the best system for that as you need a collection of different skills between the coding you need the graphics (drawing & animation). All of these really require a more powerful system as well as a larger display to work off of if you are a serious developer for Mac games. IF you are doing iOS gaming then you might be able to work in the smaller screen but I'm sure you'll want more power.

To start off which system you have will make a big difference on what is possible!
As an example: If you have iMac i5 2.7GHz system the CPU is soldered to the logic board and would require a full logic board swap out!
If you have iMac i5 2.9GHz system then you can replace the CPU chip alone! But you are limited to what Apple offered iMac i7 3.1GHz system.
Now while the iMac i5 2.9GHz system only needs a chip is the performance improvement worth it? Is the risk of damaging the system to high? Just opening the system is tricky! Many people damage the display in the process as its not easy!
Frankly, if you need performance for serious game programing this is not the best system. I would go with a 4.2 GHz Core i7 (I7-7700K), 3.6 GHz Core i9 (I9-9900K) or 3.2 GHz Apple M1/M2 system if your applications support Apples processor.
Maybe you should look as a laptop system using an external display for now like a 13" MacBook Pro 3.2 GHz Apple M1/3.49 GHz Apple M2
or wait a bit as its likely the 24" system will get the expected M2 upgrade or a more Pro/Max version iMac or Mac Mini/Mac Studio system

@danj Thank you for your reply :)
I have this model of iMac Late 2012: 2.7 GHz Quad-Core Intel Core i5
I have already opened my iMac 2 times, and checked what processor exist, its i5-3330S, as like normal PC processor.
So that I considered it for the upgrade and round $120 to $150, I will found processor from the market.
As per support, it will support i7 3770s processor.
I have already upgraded with 1TB SSD and 16GB RAM within my iMac and I don't have performance related issue.
To make it work more better, Is it worth to spend more for processor?

I converted your question into its own as you had dropped it in someone else's question which is a different system, so all of the examples I posted above don't apply!
