Expreview has got its hands on the NVIDIA Forceware Beta Driver 180.32 and used it to setup and enable SLI with two Galaxy GTX260-216, on an Asus P6T Deluxe motherboard. The cards scored a 3DMark Vantage score of P21623, compared against a single card score of P10920 gives an approximate 98% increase. Currently it is only possible to enable SLI officially on NVIDIA based chipsets, only AMD's equivalent Crossfire system works on Intel chipsets. It is evident that the 180 series of Forceware drivers from NVIDIA (dubbed Big Bang II) not only brings multi-monitor SLI support, but also paves the way to enabling SLI on the Intel X58 Chipset. In another article, Expreview have also mentioned that the beta driver 180.42, will be officially released from NVIDIA later on today, with the final version set for November 17th this year, coinciding with the launch of Intel's Core i7 and X58.
