I used to use Cubase all the time, it isn't for the faint hearted, if you're not fully PC literate you will struggle. The problem with it as far as my experience with it is that it's orientated to having several synths hooked up to it not manual programming. I used to program it by hand myself and make my own sound effects, my DJ boss at the time thought I was mad. Later I got in to Reason which lends itself more to hand grafting things and comes standard with an amazing array of instruments and effects including hundreds of quality drums and accessories. I don't write music much any more but I still use Reason on a regular basis as a drum machine and metronome mainly, I recommend it highly.
If you want drums try Reason.
