One word - noun. Two words - verb.
"I set up my new system recently. Pretty decent setup." Good.
"LD hasn't setup FC2 on his system yet." Bad.
Also, despite common usage "times more than" is ambiguous enough that it shouldn't be used. Technically, "5 times more than" (or "5 times faster than"...) would mean _6_ times as much as (or as fast as) the reference sample.
Put it this way...if Joe has a dollar and Tim gives him two more, Tim has given Joe two times as much as he had. Joe now has two times more...or three times as much as he had before.
Don't even start with "times smaller" or "times less than"
