I currently have the gtx 580 standard video card. I am considering running dual graphics cards soon. The second one I am considering buying is the gtx 570 superclocked. So my first question is; if I ran these two together which one should be my main one. Because from what I have heard you get the full capacity of one and only a certain percentage of the other. So I guess it most likely simply boils down to which one is more powerful? Any insight on that would be helpful. My second question is; if I ran these two together what kind of power supply would I need to have. And I would preferably like to know what power supply would be a SOLID amount, not just the bare minimum. Thanks in advance.
While they use the same type of card, the GTX 570 is basically a GTX 580 that has a few things disabled or completely cut off, much like the 560ti has more things disabled and it goes down from there. Because the gtx580 actually needs these parts to operate, it can't be paired with a card that doesn't need the parts.
Think of grabbing any random car's enginge and throwing it into another car. All in all, its the same basic parts and connections, but they just don't go together and wouldn't run correctly. Same basic concept with the cards.
