There's really not much point to LGA 2011 for an enthusiast. LGA 2011 is for people in situations where time means money (because of the 6 core i7's for video editing, 3D modeling, etc.).
I know there are "enthusiasts" out there that have LGA 2011 systems, but it's more of a "hey, look at what I have" thing than anything else.
Yes, LGA 1155 is already dead in the water, as far as upgrades go, but LGA 2011 might be, as well. There's no guarantee that IB-E will be on LGA 2011 (or that IB-E will even exist).
My recommendation is to go with LGA 1155 (Ivy Bridge). It'll last just as long for a fraction of the price.
