I just downgrades to a gx260 to save some money and now im thinking of throwing in an old video card to play CS:S. I am looking at a 9800, 9600, or 6600gt, I would rather grab a 9800 or 6600 but concerned about the power supply, it has 250 watt, I am pretty sure it would just not work with the 6600 but on the 9800 they "recommend" 300W but do not require it. I have 1 disc drive, 2 hard drives, and a usb external DAC. Will I need to upgrade the PS to use the 9800, has anyone ran a 9800 on 250W power supply??? Thanks
