It seems you kinda new in this werld...but nevermind, everyone's the same...

C'mmon let me tell you a story...

GC is made for displaying digital information such as colors,coordinates, in other words what you are seeing right now on your screen....See this smilie? -->

GC process the data and then transmit in on to your monitor via a cable which you usually take off and plug it back everytime you wanna move your computer someplace else...If you are using a notebook than don't read this...

Beside displaying all the beatifull pictures, colors, views and scenarios....it is also being built to support math programming which usually used by the gaming industries to create the ultimate 3D world and realism as real as it can be....Dont trust me? Try playing DOOM3 alone in the dark at 2 am...then tell me what is not true...

But then there lies a problem with too much realism....It need super duper fast processors to generate all the data/multiplications/add/subtract/times and other math terms (which sometimes even me myself dont understand)....without superfast processors, the outcome will deteriorate and wont be as real as it should be....

So whats the point of overclocking a GC you ask? The answer is NO Point At ALL...

Most people who overclocks their GC are bench-scores addicts....my advidce to u is better u don't be one of them or else, you'll have no life, no money to take your girlfriend out, not enough sleep at nite, eager to squeeze every milliinches of graphic processing power your puny GC can produce, sucking it dry and in the end blowing it up for what? A 20 marks diffrence from another bench-score addicts on the other side of the world...to me...that it is just plain waste of time...

Unless you're talking unlocking 'hidden' pipes, or additional processor memory integrator upgrades....Just keep your GC safe and sound running at factory clock speeds....

But then who say's you cant give it a try????
