Depends on your current setup. If you haven't overclocked and your CPU user < 95w (125w may be pushing it, but there's a good chance you may be able to go up to there) I'd say go for it. Otherwise, you could easily go over your power supply's maximum. Also, if you do go the route of getting another PSU don't choose a bad brand (Corsair is good btw).

Perhaps but there are limits of current on a particular "rail" inside the PSU. You should contact Corsair or Nvidia webpages for details.

no problem! the GS600 has enough power as it has a single +12V rail providing up to 49A. this is roughly your build (2x GTX 660 OC and without case fans) after my calculation the max. power consumption is approx. 470W. the estimated wattage of pcpartpicker (456W, in the upper right corner of the site) is slightly less because they don't take into consideration that the overclocked GTX 660 uses more power than the regular one. on the other hand they calculate too much for a hard drive (20W, effectively it's 12W).
