As far as for performance... no it's totally not necessary. Intel has what can only be considered ungodly QC - since in all my years of building systems I've never gotten a bad one... and between myself and workstation builds... I've built somewhere in the 700+ range of systems from 386s to the current gens. On the other hand there might be a very good reason to consider doing it - die lottery. There is a huge variance between OC capacities - and as someone who had a 3770K that liked over 1.4V just to see 4.7GHz... if the place you purchased it from has a good return policy, use it
Try it out and see what your OC looks like in stock form... remembering that although your temperatures will get better after you delid - your voltage requirements will not (or will only very, very slightly based on a lower overall temperature). If it is great as far as voltages are concerned, but gets really hot - especially if there is a big difference between the individual core temps - then by all means delid and go for the gold. On the other hand if you're over 1.3V just to get 4.4GHz... regardless of what the temps are, you might be better off just returning it and trying a different chip.
As with anything else YMMV - and if you're not really concerned with OC potential, then this might all be academic... but if that's the case you wouldn't be getting a "K" SKU chip and you wouldn't be in this thread on this forum - so that's why I bothered writing this.
