How to SLI

Hi everyone!

I am going to be purchasing 2 x EVGA FTW GTX 670's on Friday, to replace my current 1 x Gigabyte Windforce 670. Obviously, I am planning on SLI'ing these 2 cards. :) My questions are:

1. How do you actually set up SLI? I know that you need an SLI bridge that you connect to the card via the SLI connectors, and I know that you need to set the Nvidia Control Panel to use the SLI. Is this is or is there anything else that I have missed?

2. I keep hearing people mention about having three cards, but only 2 of them are in SLI and they use the 3rd as a Physics processor? What is this? Would I benefit by using my Gigabyte 670 as one on these? If so, how do I set this up?

Thanks in advance for any help!

    That's pretty much it.
  2. Bump

    Can anyone please give me a detailed crash course (If that makes sense! =P ) on how to SLI please?

    I am ordering my cards in 4 days and will be paying for them to be delivered on Monday so I really need to know what I am doing.
  3. Don't bump and there is no crash course, you covered the sequence in your first post.
