My 6800Ultra has died on me so I need a new AGP card. Problem is my PSU isn't the greatest, I only have 14amps on the 12volt rail so no chance of the X1950 Pro. That doesn't bother me as I don't really game that much on the PC anymore. Really I just need a new graphics card for basic PC stuff, the most extreme thing would be watching HD Video. I would also need it to be able to run a secondary display. I have no idea what card I should be looking at these days that doesn't require a lot of power to run it. 6800GS? 7800GS? 7600GT? Those possible?
