Well I am reading more and more about Power supplies, and it seems to be that having dual 12v rails is better. Since I am getting a 7800, its recommended that I have one rail to power that and another to power the rest of my system, right? But even if thats true I am concerned that I won't have enough wattage with this PSU http://www.newegg.com/Product/Product.asp?item=N82E16817103460 because I know the 7800 alone takes up 250 watts. How much will everything else take up?
