According to Ingo Bauer's list, Deep Rybka 4 has a very small difference of 6 ELO point more to Rybka 3 mp, see the following URL http://www.inwoba.de/bayeselo.html

You are comparing Rybka 4 Single Core with Rybka 3 Dual Core !
List of best single engines, one engine per Author (basically all one may need):
Name Elo + - games score oppo. draws
1 Deep Rybka 4 2949
2 Stockfish 1.7.1 JA 2884
Full list - including 2-core engines:
Name Elo + - games score oppo. draws
1 Deep Rybka 4 2949
A Rybka 3 mp 2T 2942
B Stockfish 1.7.1 JA 2T 2927 2 Rybka 3 mp 2897 3 Stockfish 1.7.1 JA 2884
C Naum 4.2 2T 2881
The engines with (2T) are using 2 threads, otherwise it is only 1 thread
So Rybka 4 single core is 2949 and Rybka 3 single core is 2897. Thats +52 elo difference
You can also see that Stockfish 1.7.1 JA Single Core is 2884. So Rybka 4 is +65 elo better

He has the right to do what he wants. If people want to spend their money for a 25/50 point upgrade is up to them. I don't care either way. Chess in general and Rybka in particular are not very important in my life these days.

if you can win it, it is not worth your bucks.
If it is not worth your bucks, you are a chess genius
If you are so, what a HECK are you doing here, home of incapacitated players?

So, just as you might get a calculator because it can do work for you, so can a chess computer do work for you, and let you know if a sacrifice is sound, or if a move is good. [That is quite interesting to ME].
Certainly with just playing them I get lot of fun and I Do learn something each time...sometimes.
Problem is I always learn the same thing and I always forget it.
I cannot convince myself that to learn chess seriously beyond what you learn without effort, with time, is worth the effort.
I think it is not and I save my mental powers to other endeavors.
So.... I can still be caught by a XV century opening trap regards

I'd have to disagree. (And I don't even have R4 yet )
From what I've seen, it looks like it's packed with useful/interesting stuff. And hey, it might be the strongest engine in the world. (We'll have to see if Fire 1.3.1 catches it.)
BTW, I'm not a Rybka "fanboy" but I'm not really a "Robbohooligan" (to use I think it was Miguel Ballicora's term). I do however believe that the Ippos are NOT clones, but they certainly used some ideas from R3.
