|The card will work as a dedicated (Primary) card in any mboard that has an Intel, AMD, NVidia, or Via main chipset regardless of whether you are able to run it in SLI mode, but if you were to run it in combo with another applicable NVidia video chipset card (two PCI-E X16 cards and two slots required, or one X 2 card with two of the same video chipset) , or in combo with the onboard video if the main chipset supports Hybrid SLI video if applicable (that is only supported by a few specific NVidia video chipsets on the card) , on a mboard that has a NVidia (or some Intel) main chipset(s), you will be able to run it in SLI mode and get better overall performance.|
If the NVidia main chipset supports Hybrid SLI video, and if the Nvidia video chipset on the PCI-E X16 card is one of the few that supports Hybrid mode with that main chipset, both the onboard video and the video on the card are or can be enabled at the same time and are or can be running in SLI mode.
In don't know anything about which Nvidia video chipsets you can use together and have them run in SLI mode, but for ATI video chipets to run in Crossfire mode, the video chipsets do not necessarily need to be the same
CrossfireX Combination chart:
The ability of the main chipset to support Crossfire or SLI mode is not limited to just AMD main chipsets for Crossfire, or NVidia main chipsets for SLI.
Some of the Intel main chipsets also support CrossfireX mode
Some of the Intel main chipsets support SLI mode.
A few Intel main chipsets support both, as in, for two ATI or two NVidia video chipsets .
