There is no advantage because:
1/ all critical processes are executed in double precision anyway.
2/ The advantage of double precision in the "adders" is cancelled by the reduced bit-strings in the SSE registers. While a CPU register can hold registers up to 80 bit and more, an SSE register can only hold 64 bit strings. So the precision you might gain (and since it's only adding & substracting numbers, the errors can't be cumulative) by summing in double precision for adding/summing and the likes, is lost by the rounding that takes place when the 64-bit registers are full.

Yeah - but - uhhh - "64" is higher than "32" - right?

So - uhhh - 64 is better, then, right?
