Positive. Though, you can get a faster chip by opting to get something like a -1680 v4 or a -2687W v4 which should be plenty good. The i7-6850K has devalued quite a bit and should clock high, too.
Posting my quick reference (it's mostly accurate as far as I know):
LGA 771: Core 2 Extreme QX9775 only,
all Xeon-branded processors are locked
LGA 1366: Core i7 Extreme Edition (i7-965, 975, 980X, 990X), plus Xeon W3570, W3580, W3680, W3690 are unlocked,
all other models are locked, though BCLK overclocking is possible
LGA 2011: Core i7-3820 and Xeon E5-1620 are
partially unlocked and have a maximum multiplier of 43x; Core i7-3930K/3960X, i7-4820K/4930K/4960X, E5-1600 and -1600 v2 families are unlocked,
E5-2600 and -2600 v2 CPUs are locked
LGA 2011 v3: Core i7-branded parts, i7-5820K and i7-6800K are
fully unlocked but restricted to 28 PCIe lanes, Xeon E5-1600 v3 series only:
E5-2600 v3, -4600 v3, all v4 CPUs are locked - including -1600 v4
LGA 2066:
all Xeon-branded processors are locked
LGA 3467: Xeon W-3175X only,
all other processors are locked
