Not to mention that lvl 80 bow is NOT the maximum for bow, just that the sites and the brady games book don't mention it.
For instance, at 175 you get Sidewinder, which is hands down the most damaging skill in the whole game... I've heard stories of 1k+ damage with it.
But yes, +accuracy is ALWAYS good. I saw a rng in AF armor, half the stuff he had increased dex/agi and had ranged accuracy boost as well.
