To the OP, could you be a bit more specific on what system you actually need a power supply for. Because i'm just guessing on the GTX260 SLI here.
"LF 600-750W psu", this isn't WoW trade chat you know. Be a bit more informative.
Honestly though, something like a GTX660 will outperform those two cards at a quarter of the power consumption. It seems a bit tacky to me, but hey...
