Something just came to mind regarding your mondo monitor. Are you using a dual-link DVI cable? Check the connectors on the cable and make sure that it's got a single group of 24 pins and not 2 groups of 9.
Probably a dumb question, but you might be using a different cable with your new video card and I just wanted to be sure that it wasn't the cause of your problem, however unlikely that may be.
Also, since you're playing TSL again, are you going to give TSLRCM a try?

Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
