So now comes the decision of which way to go.

Asus 2Gb 680 is $699, Asus 3Gb 7970 with 6 outputs is $679.....

The slight extra speed of the 680 does not seem to outweigh the extra framebuffer size and ability to run one character per monitor fullscreen of the 7970 but am interested in others opinions before I pull the trigger next week.
