Asimov - Fountains of Paradise
Kim Stanley Robinson's Mars series.
Frederik Pohl's Gateway.
I'm going to echo the recommendation for Cryptonomicon too.
Basically look through the history of winners of the Nebula Prize and see what interests you.
Outside of Sci Fi (but not far outside), I tell everyone who asks for a book recommendation to read Haruki Murakami's Wind Up Bird Chronicle.

Haruki Murakami's Wind Up Bird Chronicle
or anything by Murakami, Hard Boiled Wonderland and the End of the World is amazing too.

I LOVE Murakami.
His latest was a bit hit and miss, his books are dreamy though.
