Okay, here's my question, I have seen a lot of people talk about over clocking the chip. Mostly when building PC. 1. Example, making a chip that is a 2.4 run at 3.6. 2. Can Mac's be over clocked? 3. How do they over clock a chip to run faster? 4. I am guessing the up side is a faster CPU, what are the downsides?
