So im thinking of a new build soon, but i want it to last for a while. I figure the best way to do that is make sure that the mobo can support the next couple generations of CPU so will intel (because i prefer intel CPU's) switch sockets anytime soon because im a bit confused as to the 2011 socket.
More about :intel switch cpu sockets mobo insurance
Word seems to be that Haswell will use a new motherboard socket, so 1155 is done for. However, its not really practical to choose your platform based on drop-in processor upgrades anyway.. sockets don't stick around that long anymore. Plus, a modern Ivy Bridge (or even Sandy Bridge) processor is probably good enough to last you through the next socket anyway.
Only the Sandy Bridge E Core i7's, like the i7-3930K, -3970X, etc, use LGA 2011. It likely doesn't have a bright future either.
