I guess having a more kickass system that can deliver more power to the video card definitely helps its chances at being stable at high clocks. So does setting up a custom fan profile in MSI Afterburner so it stays much cooler than the default setting lets it go. Before I swore this card was an awful overclocker, but this is what new stability testing has proven to work solid stable so far. Note that the RAM is awful and if I turn it up a few MHz more it begins to artifact after not long. However, with just these clock/shader OCs I get about 25% whopping more FPS. My minimum FPS in COD4 went from 14 with a slight OC to 19 with this OC. Not too shabby and MUCH more playable.
