There is parallel sequence scanning coming in 9.6 -- http://rhaas.blogspot.com/2015/11/parallel-sequential-scan-is-committed.html 

And there is the GPU extension - https://wiki.postgresql.org/wiki/PGStrom 

If those aren't options, you'll want your table as much in memory as possible so your scan doesn't have to to go disk.
