You don't want to go 1336 matey as its an older enthusiast socket that has no upgrade path. I currently use that socket and despite my processor (see sig) still handling anything I throw at it when I upgrade its going to mean I have to replace motherboard, memory and processor. The 1156 / 1155 are not the upgrade to the 1336 but run faster and are very good overclockers. 1336 upgrade / replacement is the 2011 with Sandy Bridge E processors.
They all have good processors attached to them but to go 1336 now would be a bit of a waste and possibly difficult to find a wide selection of parts.
