probably want to update your video car drivers.
1- Reinstall drivers to your video card2- Reinstall chipset drivers for your motherboard3- Reinstall latest version of DirectX4- An option called "Enable Write Combing" under the "Troubleshoot" tab advanced display options. this option, when clicked, accelerates the display on your screen, but may cause corruption.5-This could be a hardware or overheating problem. Check the fans/temps in your case (specifically the video card) and is your card overclocked?6- You can try changing multisampling options in wow, too.BTW, post your video card / OS?I'd put my money on #5 though.

The Radeon X1950 Pro behaves differently. Like all modern graphics solutions from ATI Technologies, it loads the +3.3V line heavily. It also puts a higher load on the internal +12V line in 3D mode than on the external one.
Sounds much better. Hopefully that is a name brand like corsair, antec, enermax, or seasonic?Your old one had waaay high and low 5v and 12v rails, respectively.
