It depends on what you max first.

If you max Q, Luden's, Hextech Gunblade, or Sorc Shoes are all good rushes.

If you max W, Hextech Gunblade, Haunting Guise, or Abyssal are suitable.

Depending on your masteries, you should either build lots of flat AP or focus on Magic Pen.

Flat AP: Luden's, Zhonya's, Rabadon's, Void Staff, Rylai's/Gunblade, Sorc Shoes/Lucidity.

MPen: Abyssal, Haunting Guise, Sorc Shoes, Void Staff, Sorc Shoes/Gunblade, Sorc Shoes.
