We do actually expect people to go that far in the 'Optimal Sets / Item Discussion', is there is a small yet significant difference between precision and a lack of precision. So the poster you're responding was well within their rights to correct you, so there's no need to act pissy about that.

Gimping your DPS for 4 mins, 40 seconds is not worth the advantage of being over the GCD for 20s. Obviously the disparity gets even larger as fights get longer.
I don't think I made myself clear, I was talking about mage fireball spec. With more than 781.59 haste and taking into account only Wrath of Air totem (100% uptime) + Swift Retribution / Improved Moonkin Form (100% uptime) + T10x2 bonus , you get your GCD < 1sec. So its not a 20secs situation... Now you can add into account heroism, power infusion, black magic proc, haste potion, etc and find a number that better suits your fights. I said 800haste for the sake of easy math calcs but I guess you'd rather say I'm wrong rather than do the maths yourself.
