Think of it this way, everyone has a style and things are going to start sounding similar the more tracks you make so when you get to that point just try doing something different with the sounds, Different Effects different eq. Even the best producers who stick to software won't have 40 vst's the trick is figuring out how to continually evolve what you have. The first thing people think about is I need another vst but they abandon the fact of getting more effects; or with the effects they have they don't alter them. There's just so much you can do to get a different sound. However, don't be phased by something that just sounds like your style. In fact if you have your own sound with no matter what you do that makes you all the more valuable as a producer.
I hope this helps
Edit As for the beats themselves they don't sound the same. Probably the same feel but they don't sound the same themselves.
