I just read Tom's and [H]'s reviews, and it looks like an amazing card.
One thing that I don't understand, though, is how the new "Eyefinity" technology on these cards differs from previous cards. Is there something special about the inputs, or does it allow you to use dual-screen resolutions with games that didn't previously support it?
I first tried dual-screen gaming two years ago; I played Portal on two 19" monitors (2560 x 1024 rez), and that was with an old Radeon X600. If a Radeon X600 could do that, then there's no way that newer cards couldn't do it. What's the difference with Eyefinity (stupid name)?
The difference is that with the older multi-screen implementation, the screens were reported to the OS and to the games as two separate screens. Eyefinity combines up to 6 screens into a single large virtual screen, so as far as the game knows, you simply have a really wide screen. All the game needs to support is a non-standard aspect ratio, wheras before, it had to explicitly support multiple screens.
