Ok, so it definitely overclocks the lower one and doesn't underclock the higher one? If so that is very good to know
I was wondering the same thing as the OP bc I have a 9800 GTX+ Superclocked, and I was thinking of doing SLI. The problem is that newegg doesn't carry that one anymore but they do have the 9800 GTX+ standard still. And what happened to all the nvidia cards? Newegg took a ton off that they used to sell; there aren't many 260's or 280's or anything anymore. I was really confused lol.
