The board im purchasing I think supports both things, but if crossfireX is sometimes not supported is this not the same for SLI? If its not why isn't everyone just using SLI or have I missed something vitally important about SLI?
The bridges are generally supplied with each Video card, and sometimes with motherboards.
CF and SLI are supported in both cases regardless if one is supported.
Support is from having 2x PCI-E Slots that are running at least 8x bandwidth on both. Not sure about SB builds but almost all of the boards should be.
As for the video card, I highly recommend going with 6950 2GB and flashing to 6970, amazing card for the money in that bracket nothing beats it $/fps.
I'd recommend getting one for time being since thats more then enough to run just about anything under the sun unless your planning on running Eyefinity/Surround.
