What needs to match for SLI?

post #1 of 9
Thread Starter 
What matters? Is it just model (460,560, 570, etc) and ram? Does the brand etc matter?

Brand doesn't matter, it's just the model. 460 with 460, 580 with 580, etc.

You can SLI them but as stated above it will use the lower total so it is a better choice to use matching cards.

Brand and clockspeed are agnostic. As long as the models are identical you can run any two cards you like. (But not GTX460 768MB and GTX460 1GB for example, as they are different models).
