Ah, so you lead me to more questions... It seems that a lot of people overclock their GPU, whats the pros and cons? And exactly how do you do it? Same way with the CPU?
It is done using software. Rivatuner is what I use and it's compatible with both ATi and Nvidia GPUs.
- Faster GPU, higher FPS.
- Higher temps if the fan speed is not increased.
- Increased power consumption.
I usually start by clocking up the core first, increasing it in small increments whilst playing a game until I start to see artifacts, this indicates instability. I back off slightly, play for ~20min and if all is well I move onto the memory and repeat the process.
