Sandy Bridge is the new next gen Intel Processors.
Did you order one of the SB CPUs? eg: i5-2500 or i7-2600 ?? If you did, you should have already been contacted about the recent problem with the SB chipsets and offered various solutions to choose from.
If you didn't order a SB CPU and went for one of the older, but still great, i3/5/7s then you won't have any problems.
