    Hey,

    what's the difference, would you say? How much more would you pay to harness two 560s, opposed to one 485? Which would produce more heat? Thanks

    I think two 560M's are equal in price of one 485M I think and in terms of heat, if the SLI configuration for the 560M has each GPU with a dedicated fan and HSF unit in a big enough chassis, than the 560M SLI might still generate less overall heat than a single 485M.

    I think, correct me I am wrong from an SLI nVidia expert.

    485m would produce more heat (since it is a 100watt gpu in comparison to 75watt gpu), at least I think. If I had to choose, I probably wouldn't pay much more than the price of a 485m (couple hundred max). A 560m is a newer architecture overclocked 460m, and two 460ms in SLI were roughly equivalent to a 485m. So I don't expect to see more than 15% gain over the 485m (20 is pushing it), so I would pay roughly 15/20% of whatever the price of the 485m is more for a 560m SLI

    For a laptop? Are there any available with dual 560ms?

    Alienware m18x now has the 560M option or it is coming really soon...

    Two 560's (per the OP) would be 150W vs 100W of the 485. So you get more heat from two 560's and about the same amount of power (same amount of shaders, slightly higher clocks). If SLI scaling is particularly bad in the game you are playing the single 485M will beat the dual 560M's.
    Since one 6970 is about equal to 1 485M, a single 6970 will also equal or beat 2 560's.

    Right, I was just about to say, SLI has too many problems, better to stick with 485m, or better yet just go with 6970m.

    The issue is more complex: not all games have the same performance in SLI. I am not sure where the 2*560m = 485m relation comes from, but bear in mind it is not equal for all games (for instance, at 1080p SLI currently can give between 50% to 90% faster performance versus the same single card).

    Therefore I would say I wouldn't pay more than a single 485m.
