Well... a lot of the other factors are important.

Are the players behind you likely to call two cold? Then raise by all means.

Is the player who led out likely to lead out the turn? If not, then raise for a free card.

Are there lots of players behind you? Then you might consider going for overcalls.

Did you raise preflop? And get bet into anyway on a scary board? These affect how likely are you to get 3-bet.

Heck--- is the nut four-flush with two cards in your hand or not?

At a minimum I think you need to know the number of players to have any chance of answering this correctly.
