Customizing your computer can be a costly thing. Anyone who does it knows that. And, if you're a gamer, or someone who needs their computer to be the best on the planet, it can be downright ridiculous. Take, for example, the Sapphire Radeon HD 5970 TOXIC Edition, which is surely going to cost you somewhere in the ballpark of $700. But, at least it's the fastest video card on planet Earth. So, you get what you pay for.
