3 monitors

I want to be able to run 3 monitors 2 standard and one big one all running with the same display.

Will I need to look at SLI?

Any one got a setup like this who could offer an insight please?

Thanks

As your current card has two connections, you need a second card... you figured that one out already I guess. Question is what you want to do with the 3 screens. What do you mean exactly by "running with the same display"?

However, in my experience, the nicest way is two identical cards on SLI. If your MOBO can fit that....

I want it so the 2 smaller displays are extended and the bigger one just a mirror. Recommend any cheap cards for the job?

I ran a GTX285 and a 9600GT to run my screens and then I upgraded to an ATI HD5850 and run 3 screens off of that one card.
