I'm not saying RB is all he will ever need. I have other programs too. But the OP is buying Biab. RB is a natural extention that (in my eyes) qualifies as a DAW. I still don't think he needs to buy another DAW until he decides he can't do what he wants with the included stuff.

Another poster commented about needing an expensive system to run RB. I have found that not to be true in my experience. I know of a half a dozen systems that are over 5 years old that run recent versions of RB just fine, and none were real expensive to begin with.
They are set up to be audio machines though. Taking a few minutes to set up your OS for audio can make a huge difference.

I do not work here, but the benefits are still awesome
