Word is quickly spreading in regards to a superior version of NVIDIA's SLI technology, simply dubbed "SLI 2.0" (at least for the time being).

VR-Zone first published some brief info on it in which they've learnt that the updated tech is set to launch during CeBIT in March.

At this early stage, the only supposed benefit from it over the type of SLI we're currently used to, is that it will be capable of working with mixed cards (though its still unclear as to whether or not this means it is across different series or different models of the same series..).

Though quite scarce at the minute, you can get some more info on it over at VR-Zone, XBit Labs and Nordic Hardware folks.

XBit:-
Nvidia Corp., the world's leading supplier of discrete graphics processing units (GPUs), is reportedly planning to update its multi-GPU SLI technology in March to enhance performance and features, thus making SLI more appealing to computer enthusiasts.

The so-called Nvidia SLI 2.0 technology - which, according to a news-story over VR-Zone web-site should be unveiled at CeBIT 2007 - should support work of 4, 6 and 8 graphics chips in parallel as well as support different graphics card's operation in tandem. There are currently no clear details regarding the SLI 2.0, but the fact that Nvidia is looking forward to improve its multi-GPU technology deserves attention.
