You know what bothers me though about these 600 watt power supplies is that they only come with normally 2 6+2 12V power adapters where you have the 750 watt that supplies 4 connections. And just because you only need a certain amount of power you are assuming that 100 percent of the time it will only use that amount.
Yup just got done searching for that power supply you linked on here. And it only comes with 2 pci-e power adapters. I refuse to use some stupid adapter for sli if that was a route someone went. http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014
and then OH MAN magic 4 pci-e power adapters. http://www.newegg.com/Product/Product.aspx?Item=N82E16817207016&Tpk=xfx%20750
