is your psu powerfull enough to power both of them?
any way start up in safe mode as i t sounds like it bsod's when the rivers are implimented for 3d.
so try booting safe mode uninstall drivers restart in normal mode then re install.

If possible, I'd suggest getting a 5800 or 6900 series card. It should give about the same performance (and a lot of new features) on half the power. You should be able to pick one up relatively inexpensively these days.
