Should i preorder cod7 or wait for the crack (solved)

I am thinking of purchasing call of duty 7 i have never purchased a game through steam (as this site gives all)
but which would be better and if i buy from amazon which has �29.99 instead of �39.99 will i still be able to get it to work with steam ??

as ive never activated a game with steam i would like to know if it works and would it be worth it or should i wait for an cracked server to be made i have used alteriw since it came out last year but there are dodgy servers and silly kids messing up the game so would it be better in the long run. and after i buy the game would i still need the dvd to play it online ? (btw i have always used no cd cracks and never needed a cd in the drive since 6 years back )
any help appreciated
also there this video where players will receive money for winning a game.

im not sure that will be in the cracked server or if it were it would be hacked throughout.
