Which computations ? A 20 bit DAC gives 120dB dynamic range .. greater than ANY analogue, and greater than any amplifier is capable of reproducing. Bob Stuart of Meridian gave a paper saying that any more than 20 bits is a waste, and DVD-audio (which meridian authored) is only 24 bits because most commercial DSPs use 24 bit word length, and it makes mixing easy (no overflows).
Sampling rate is probably more important one you get above 16 bits.
But ultimately implementation and design matters more than miscellaneous specs.
