Dual Graphics cards SLI

  isca2 10:42 05 Jan 08

Am thinking of having 2 graphics cards in my new pc. Being new to this, can someone explain how this works. Do I need 2 DVI connectors to the monitor ( not sure if the monitor has two inputs ! ) or do the cards somehow link up together and act as one with just one lead from one of them to the monitor?

It's just one cable from one of the graphics cards to the monitor. There's a bridge link internally, supplied with the motherboard, to connect the 2 cards. Also, there is usually some sort of adjustment to the motherboard to switch from normal to SLI mode. The motheboard user guide will advise on this.

Thanks QuizMan, thought that might be how it works.

I know you have ticked this as resolved but you might want to reconsider having two cards.

The general consensus is that one good one is better than two mediocre ones and in addition you will get twice the noise from two cards as well as a bigger power requirement from your PSU. One other thing to consider as well is that SLI drivers are not yet as reliable as standard drivers.
