Spending $1000 for a cpu only in a dead end socket mb (1366) only to have it's performance equaled in games by a $230 i5-2500k.... PRICELESS
(I would not ponder the 6/8 core cpus until they at least at least catch up with quad cores in gaming performance)
WHat is the resolution of your 47" LED? If merely 1080P, pretty much any $1000
rig (i5-2400/P67/6950 can game well on it.
