Hi, I am new to this group. I need a processor for software development purpose please suggest a cheap and best configuration with AMD processor + mother board+ram.

Your budget is so low that it's going to be really difficult to recommend a good build.  Given that you aren't gaming I would look into an FM2 setup using an APU.  I would look for something in the A10 family if possible. I'm not sure what you have for options so i can't really recommend exactly which model of CPU and motherboard. I would get at least 8gb of RAM preferably 16gb given what you plan to use it for but that's going to eat up a lot of your already minimal budget.
