Now that I have had my first success overclocking the i7 940 I'm feeling a little cocky.
Is it possible to tweak the GTX 280 to add to its performance?
It is quite possible. You need two programs, RivaTuner and Furmark. RivaTuner does the OCing and Furmark stresses your card to test the OC. The method is to open RivaTuner, go into the customize button of the driver settings and select System Settings. Open the fan tab and change to direct control. Set the fan to 85%. Move back to the overclocking tab Tick the "Link clocks" button and start SLOWLY moving the top two bars (Core Clock and Shader Clock) to the right (they will move together). Raise about 5mhz at a time and test with Furmark for each one. When it becomes unstable knock it back to the stable setting. Next move the Memory Clock to the right at about 10mhz at a time until it becomes unstable and move back to a stable setting. When you have found what works, set your settings and tick the "Apply overclocking at Windows start" and set the fan back to auto control. The point behind setting the fan at 85% is if it is stable with the fan locked at 85 it will be stable during games when the fan goes up to 100% and it will give you a little breathing room in the temperatures.
How would this method fair up on the 285 Super Clocked edition?

I messed with the standard EVGA Precision tuner program that comes with the card and I found that even if I tweeked the sliders up a little bit the system became unstable. So I have just left it as is out of the box with the latest drivers. I would however like to get more out of the card if possible. I also noted when I did raise the sliders there was no noticeable difference...that I could see at least. What do ya think?It is quite possible. You need two programs, RivaTuner and Furmark.
