Scalable Link Interface... it basically means you could buy a second graphics card of the same model and connect them both together to increase your graphics processing power (assuming your motherboard supports SLI)

Scalable Link Interface is what the acronym stands for. It's a technology for Nvidia GPUs which lets you use two compatible Nvidia Geforce cards together to boost performance. The equivalent AMD Radeon technology is "CrossfireX," or xfire for short.

On that point: most any board will support a single card from either manufacturer. TO use two (or more, in extreme setups) cards together in SLI or Xfire you need a compatible board.

Hi,

SLI stands for Scalable Link Interface, and should not be confused with the older, defunct, and somewhat related technology from a different company, Scan Line Interleaving.

SLI allows multiple NVidia GPUs with similar architecture and configuration to be coupled together to both chip away at alternating frames of the same render task. In gameplay, this can improve frame rates by up to 100% while injecting only a very small (not noticeable with two GPUs) amount of input lag.
