Running at near-stock speeds on my 5830 seems to be much more stable. Damn. I'm reluctant to reinstall drivers, because I had a hard time getting both 5830 and 6950 drivers correct and both recognized by Windows in the first place.

What is weird is that my 6950 is in the x16 slot (you would think that would be the primary video) but the 5830 in the x1 slot is where the monitor output is when the system POSTs and shows loading Windows, then the primary desktop is on the 6950.

Is there some setting I am unaware of to select a "primary" display card(or slot) either in the BIOS or in Win7? Hrm, maybe a new MB is in order, perhaps with at least dual x16 slots. I have been thinking about it anyway so I could have the option of adding another GPU if I get a case location figured out.
