Is there anyway to OC your GC? Also does the Red Switch on the back of most PSUs work and what does it do?
Yes, there's tons of ways to overclock your graphics card. If you have a Nvidia card, there's a hidden overclocking feature built into the official ForceWare drivers.
I'm not sure if ATI has that yet, but for ATI (and Nvidia) there are plently of overclocking programs available.
And the switch on the back of your PSU switches between 115V and 220V input for use in countries that use different voltages in there power lines.
If by 'oc' you mean over clock, and by 'gc' you mean graphics card, then yes, its possible.
The red switch on the back of your PSU isn't the on/off switch, it's the voltage switch. Europe and the US use different voltage levels for any equipment that requires electricity. Do Not fiddle with that switch, it could destroy your PSU if you set it wrong.
Ahh...Thanks for the PSU tip. Umm....regarding the OC GC quesiton. I have an Nvidia GC and I was wondering how can I get to the OC section of the ForceWare drivers.
Install the Coolbits registry tweak, then go into your Nvidia Control Panel and go to "3D Settings", then go to "Change Overclocking Configuration".
Note: For some odd reason I can't access that on mine even though I know that is the way. Anyone care to shed some light on this? Thanks.
Can I get that directly from Nvidia?
No, the best place to get it is nVIDIA Geforce 8800 8600 7950 7900 7600 GT GTX ATi Radeon 2900 x1950 x1900 x1800 1650 XT Pro - Guru of 3D: PC Hardware Reviews

Just a little tip, if Coolbits doesn't seem to be working after you install that tweak, log out then back in, or restart your computer and it should work fine.
