Keep it in your pocket, there's a reason it didn't catch on, probably because it was not very reliable or it sucked otherwise it would still be around today.
didn't catch on? really?
I am sorry sir, but I must take issue. LGA 1366 / X58 is one of the longest lived enthusiast platforms ever. Still quite capable today, 10 years on.
I will admit that the triple channel RAM setup is a bit of an oddity as a stepping stone to quad channel architecture, but an overclocked X58 setup is nothing to sniff at to this day.
Lots of guys plopping cheap surplus hexcore Bloomfield chips in and clocking the bejeesus out of them

Oh, and one more benefit, the last platform without UEFI, so they can never prevent me from running linux on it.
