I am Alaukik and i want to know that turbo boost is good for gaming purpose.
My specs are as follows:
intel i5 2450M (2.5Ghz) but has a oost upto (3.10Ghz) and HD Radeon 7650M 2GB graphic card.
I'm not an Intel expert, but I've looked into leaving something similar the "Core Performance Boost" on in my AMD. I've heard when you leave it on, not all of your core's will run at the highest clock speed, it will only run one core at that turbo clocked speed. You might want to look into this further for a definite answer or watch YouTube videos with people overclocking your exact i5 model. Like I said I'm running on AMD with a completely different architecture, I just want you to get the most out of your CPU.
But I do agree with the above two comment's, as far as Intel goes, from what I've read the turbo mode on those CPU's are wicked for gaming. If your system is already running great with it on then leave it on, only if you are trying to push it past the limit at 4Ghz you might want to look at shutting it.
