Should I update? Would I see a difference with a sandy bridge at 5.0+? Would a see a difference with an Ivy at 4.6? How much of a difference would there be if there was one?
Also, will an Ivy at 4.6 be better or worse than a sandy at 5.0 and by how much?
I'm also considering the Ivy Bridge-e cpus depending on what is coming down the line to replace haswell chips.
