For what purposes you need it? For mining it is really low. If you want to catch some profit - you can try wallet mining with new shitcoins without pools
I was going to build myself a new PC and I am not sure what CPU to buy. I have limited budget and have to think about what CPU I will buy. Then I googled how much can I earn with a CPU, and I did not find any information regarding hashrates of CPUs
If it will be home or work PC - choose CPU for yourself, not for mining. Profit from mining with CPU is so small, that your ROI will be about 2-3 years with any CPU.
