2 video cards are better than one because you have 2 eyes.
Most inportant things in the human body come in twos.
If they don't come in twos the are heavily reliant on a pair of something.
If you think about it, you know I am right. Yeah, thats right....
2 cards are better than 1 because Im a twin...2 is always better than 1. That and if I ever won the 2 cards Id give one to my brother...even without the SLI awesomeness I know that we'd both enjoy them.
