I'm curious, we all know about the "overclocked" and "ko" etc models for GPUs. How do you overclock the graphics card? It's not like it's a setting in BIOS like the mobo, anyone want to help me out here? I got a 8800gts ont he way, and rather than spending 50 bucks I'd rather OC it myself.

Yea, people use ATI Tool to OC those cards. Give it a try.

It's quite easy, you just move sliders to change speeds, and it offers other options such as fan speed and voltage adjustments.

I've used ATI tool with my 8800gtx. It works the same as on any other card I've used except there is no fan control.

So what exactly do I want to toy with? I don't want to up the fan speed and it fry itself. That'd piss me off.

I read in one of the CPU overclocking guides that you have to lock the PCI and PCIe bus speeds, otherwise they would get overclocked in proportion to the FSB of the CPU? Wouldn't this overclock the card, or would it just increase the maximum throughput of the PCIe bus, with no effect, unless the PCIe bus was saturated?
