If you have Vista, theres your problem. Get XP.

1 char in Dal = 30fps tops on Vista, 100fps on XP.

If not, you have some settings wrong. Otherwise, you can use SLI, but you need a Matrox DualHead2go which will allow you to use the 1 output from your graphics card and stretch the massive 3840x1200 res screen onto the 2 monitors as 1920x1200 (which i assume your screens are). best bit is, you can have graphics up high as the graphics cards will render both thinking theyre on the same screen.
