Anyone have any links to teach me about SLI? I just ordered an SLI board but dont know how to do it, if the cards have to be same brand\\model etc....

Any help would be great!

First of all, fill out your system specs.

The way SLI works is by using two of the same graphics card to run them together. This is beneficial to large resolutions. Anything under 1600x1200 resolution would be a waste to go SLI. Your motherboard should come with a SLI bridge so that you can connect your two GPUs together.

Here's some more in depth information about SLI.

You need two cards that are the same model (brand, and clock speeds don't matter...however, the amount of Vram does.)

You need an SLI motherboard (of course), two cards, an SLI bridge, and a powersupply capable of running two cards.

Plug the two cards into the corrisponding PCI-E slots, and attach the bridge to the two cards.

Instal the display drivers, and go into the nvidia control panel to enable SLi (not sure which exact tab its under, but its in there).

As the others have said, your need two cards of the same model. Brand doesn't matter.

The SLI bridge should come with your motherboard. Simply plug 1 card into the first PCI-Ex16 slot, and the 2nd card into the other. Then use that SLI bridge to attach the 2 cards together.

After installing the latest NVIDIA drivers, right click the desktop, go to the NVIDIA control panel, and then enable SLI.

Also note that when you have SLI keeping the latest drivers is 20x more important because SLI sometimes causes problems with some games, and needs updated profiles to work.

Yup. If one if clocked higher then the other (If one is the overclocked or superclocked version) then put the one that isn't overclocked in the first slot, Both cards will run the clock speeds of the first card.

However if your building a new computer, I'd highly recommend just getting a single card that is faster then SLIing 2x 7600GS =/ You'd be much better off just getting a single 7800GT/X or 7900GT/X.

Edited my post. If your building a new system. SLI is a waste for lower-end cards.

Just get a single 7800GTX or 7900GTX not 2x 7600GS.
