Since we require extra power, we must also increase the voltages available to them. I'm hoping that the chances of that are pretty high, seeing as you already own a gaming PC, so you must have at least some power to spare. Make sure your power supply is a beast and can handle what we throw at it.

If you are overclocking and running your fan speeds up, you will start consuming loads more power than your system may be able to handle. So, in order to keep our parts cool and functioning, we need to ensure that our fans are cooling everything down properly, which may require an increase in fan speeds. That would cost you a lot more than a new graphics card would run you in the first place. So if you're not careful, you can actually fry components. When overclocking, the corresponding part will start throwing off a lot more heat, because it is working very hard to push itself beyond its mortal-computer threshold. However, when you overclock components, you must be careful and make sure that the machine is getting adequate power and cooling. This can save you a lot of cash when newer components come out and you don't have enough money to upgrade. You can overclock components, which essentially makes them go faster than their set limitations. When computer components are designed, they are made to run at a certain speed, otherwise known as their clock and bus speeds.
