I believe fable and diablo are older and can only use 2 CPU cores. COD4 and below can only use 2 cores but cod6 can use 3 cores. Crysis can only use 2 cores, unless there is an update for it that I don't know about.
So all in all, not worth it, in my opinion. I'd save my money and wait to get a new build instead.

Thanks. I am just planning to play COD 6 this week, and 7 is coming this winter. Diablo 3 also.
I will consider your opinion.
I guess a new MB (1156) and i5/7 may be a better choice, but new cpu, MB and DDR3 mean an extra $200-300, compared to Q9550.
I read some reviews saying Q9550 performs similar to i7 920 (5%-10% difference). Is that true?
For gamers, I think Intel is a better choice. I would like to buy AMD stuff but read some reviews you will see, AMD didn't really work well for the gamers...
I don't want to spend more on a 775 CPU either.... just easier and cheaper...
I have both CPU's the Q9550 is in the "work" machine and the E8400 is in the SLi gaming rig and I really don't think it's worth the cost to you, the difference for the most part will be minimal. Save your money for the next build.
