Imagine if you could double the speed of your car. In an ideal world you could get to work/school in half the time. However, in the non-ideal, real world, there are things that prevent that such as speed laws and the other drivers that obey them. Even if other drivers don’t observe speed laws your tires are likely not up to doing twice the legal speed limit all the time, Your engine will get hotter and the oil will break down faster. The answer is it will make your computer faster but things like hard drive access, reads and writes to RAM, video rendering etc. will all stand in the way of the ideal.
