From my experience in season3: watching stream, hearin gpeople literally say that poppy is the worst for the current meta, all of the changes nerfed poppy fairly badly.

Even with all these awsome items I can't seem to make her work on summoner's rift. I mean are we going to see some form of rework or is she just gone for the season..?

She needs a rework badly.

I've had more success in s3 than I ever had in s2. For my s3 build i use:
cloth 5 against ad or rejuv bead, charm and pots
philo stone
boots depending on matchup
triforce
gunblade
rageblade
guardian angel (get this earlier if needed)
blade of the ruined king

I've had huge success with this build, as even if you die, you should have more than enough sustain to live in most teamfights.

so whats wrong with her aside from the fact she cant farm well?

She is going to get reworked soon.

why downvote a question. Or is somebody about to give me another load of that "i assumed you were trolling" bull****? seriously people are just downvoting cuz I made them butthurt about something at this point lol

go to general discussion and search for poppy. any of the topics you find with 70+ post will answer your question
