Does anyone know how long the XFX alpha dog edition of 8800gt is?I'm wanting to put it into dimension e520,also do I need to take the stock pci card out or can I run both cards together?Im putting A 500watt/35v power supply in also.I'm hoping to find out length before buying card.If it s too long Im considering A PNY 9600gt,heard they are 9 inches long.
