Nice guide, I have this card and might consider trying this.

Two questions:

1. I'm seeing screen fractals (almost always just in the taskbar, nowhere else) when running the card on the overclocked bios bank (1GHz) while bitcoin mining (590Mhash/s). Monitor is nothing fancy, 1280x1024, 19 inch. Running Win 7 and latest driver. Is this normal/okay, and would it be safe for me to follow this guide?

2. Would you think that mining with the side panel of the computer case off would be better for temperatures inside? I do have case fans on the front and back, so I would think it would be a good idea to leave the side panel on to keep the pull of airflow going, but at the same time, having the panel off seemed to work very well at allowing heat to expel right out the side.

Thank you
