Low fps - Good specs + high resolution

So when I enabled eyefinity, my fps got even worse from 80 fps at 1440p@80hz to 7-25 fps at 3x1440p@80hz with even the lowest settings

Specs:
3x monitors (2560x1440 @ 80hz)
Radeon 7970 (3 GB) *crossfire disabled due to that horrible flicker problem
Radeon 7970 (6 GB)
16 GB 2600MHz ram
AMD FX 4350 @ 4.20 GHZ (quad core)

Is there anything I can do to increase the fps to a minimum of 50 while retaining my resolution? I know there's something wrong because apparently people can get 120 fps+ with 6850s, while with a 7970 I can barely get 80 (with one monitor)
