If we really want to be picky about the build it's about your exact purpose, and hitting the powerspikes at the right times. At 45 minutes into the game your best build is going to be IE,PD,BT,LW,boots and a situational item. At 15 minutes with around 4000 gold Triforce is going to give you more damage than an IE. After that IE+Statikk will be giving you more damage than other builds, but IE+Youmuus active combined with your AD ratios will give you the most.

You need to work out exactly when your team is going to need your damage, which typically for marksmen should be between 25 and 30 minutes in soloqueue, as average game times are slightly longer than 30 which is the point games are decided and being closed out. If you think the game will be over in 15 if you can snowball, go for an early spike, if nothing is happening or both teams seem bad at pushing, build lategame.

The final scenario to think about is survivability. As an ad carry it is your job to put out as much consistent damage as possible, using your range to survive. If survival is not likely because the enemy rengar is legendary, finishing that bloodthirster doesn't mean anything, you die in 1 second. The enemy Veigar has just hit 800 AP, Warwick keeps ulting you etc. This is when you scrap picking up that 3rd/4th item you want, and you buy Banshees/Qss/GA. Maybe even those won't work, if Zhonyas hourglass allows you to put out more than a single aa in fights, you buy it.
