Tech Report: Usually, when we're putting together an article like this one, it has an overriding theme. Either we're reviewing a particular video card, or we're conducting a comparative review of similar products. We do have elements of the latter in this article, but we don't have a single, underlying theme other than this: like high-school seniors in summer camp, the graphics cards in question here have paired up. We have CrossFire setups for the latest Radeons, including the HD 6850 and 6870, and we have SLI configs for the latest GeForces, including the brand-spanking-new GeForce GTX 580.
