Should I get Fritz 11?

I currently have Chessmaster 9000 and Fritz 8, as well as the free Rybka 2.2 download that I can use in the Fritz engine.  However, I can get Fritz 11 for $29 if I order it today.  I don't play the computer much, I normally only use it for analysis, so is it worth getting the new Fritz at a great deal, or is what I have now sufficient for what I do?  Thanks.

Well, only you can tell. You only use it to analyze. Do you have any problems with Rybka 2.2 and the rest?

I like Fritz 11. Actually sold Rybka. I think your fritz 8 has professional commentaries which i miss in Fritz 11 but have in my Fritz 7. Fritz 7 is more valuable than people realize with all of the pros analyzing their games and alternative moves.

     I have Fritz 11 and like using it as an opponent more then for analysis,

     but for 29 bucks...

I bought Fritz 10 for $10 last year. Granted, it was at a clearance sale, but it was still twenty to start with. So $29 isn't really a good price. Besides, what's with the one-day-only schtick? Where are you buying it from?

So is Fritz 10 better than Chessmaster 10?

There are other issues you should put into balance: the training videos Fritz 11 comes bundled with, access to playchess and tactics trainer. Basically this is what you pay for, you don't need yet another chess engine.
