Being that SWBF is single-threaded (as Dark_Phantom said) and server CPUs generally run at lower clock speeds, you may actually see worse performance than a regular CPU with a higher clock speed.
That being said, it's old enough of a game that it probably really won't matter and you likely wouldn't notice much of any difference either way.
