Whats a good professional beat making software?

ok so my mac just broke and i can't afford another one, i have been making high quality beats on garageband and really want continue making hip-hop instrumentals. i am getting really pissed off because all i can find is beat making softwares for beginners. what is a good professional beat making software that wont make my songs sound like they were made by a 5 year old. it needs to be for a windows vista and i need to be able to use my axiom 49 keyboard with it. im getting tired of looking for a good software when all i can find is "the perfect software for noobs" and a side question would be is dub turbo a good software?
