This is actually more of a GTX 590 question than a LOTRO question.
The GPU is not selected by GPU, it is selected by Display adapter (monitor!). Because the OP has 3 monitors, he can pick the displays. EVE happens to have a setting that somehow has an effect on his framerate. Any such setting is supposed to be automatically overridden by your ISBoxer Window Layout, which selects the correct Display adapter for each window in your layout. In your case, both of the display adapters are most likely going to be permanently powered by the main GPU.
I don't specifically know how your GTX 590 implements everything... but... with the ATI 5970 last year we had a guy that did this. The two GPUs had independent VBIOS, one for the "master" and one for the "slave". By flashing both with the "master" bios, it could act as two independent cards and power separate monitors. Something similar could be possible with the GTX 590. But, from what I'm reading about it, probably not...
