I am looking into upgradeing my video card (OC'ed my X700pro to death), anyhoo. Im running a old Antec true480, and its kinda weak for any serious overclocking as well as running extra h2o pumps and lights, etc.
Im looking at a few PSU's, whats the deal with PCI-e power connections does each card need a seperate rail if you run a SLi setup? I've heard there are some cons to running a dual rail, but no specifics?
