Congrats, Jorge! From what I've heard and seen, the 50 ASPH is fantastic. Expensive, but well worth it, especially for the low-light shooter.
My solution is to have several 50s--that way if I start to complain about one, I can use another. 🙂 I mostly use the VC 50 Nokton for available light, and a 50 Summicron for outdoors and travel. However, ahem, I must admit that I also switch between a tabbed Summicron and a DR as my moods vary.
You've probably simplified your life, as the new 50 may be the only one you need. But you may have deprived yourself of the pleasure of future GAS buildup and release. . . (or not)!
