Hi, I'm a bit clueless about this, so excuse my naivety.

I have two video cards, a Nvidia 8800 and a GT120, powering three monitors.

I run two 3D game instances (two Everquest 2 clients), one on each of my first two monitors. It's been running fine, although sometimes it sounds like the computer is trying to take off.

Today I realised that I was actually playing them on the two monitors that are both powered by the 8800. Thinking that I might as well make use of the power of both cards I tried switching the monitor cables over so that each card would be "powering" one of the clients. (Is it silly to assume this is how it works?)

This doesn't seem to have had the desired effect, as the client running on the 8800 screen is running worse than it was before.

Is it even possible to run two clients on separate GPUs? Is SLI the only way to utilise 2 GPUs? Is there something special I have to do? Or do I have to set the client to use a particular GPU (an option I can't seem to find in EQ2)?

I run the clients in window mode if that makes any difference, and I'm running Win 7.

Thanks.
