I'm going to be building a computer soon, but I have some
questions....
On TigerDirect, They had (For awhile) a Phenom 9600, ever since it
came out,
but for some reason, it's no longer on the site. It's a brand new
processor.
Is there something wrong with the 9600 or some reason not to get it
other than
it's 0.2 Ghz slower than the 9850?

9600 = TLB (translation lookaside buffer) bug.

9650 = B3 stepping, fixed

AMD changed the model number of the processor, making it
easier for customers to buy processors that don't have a bug.
So you'd want to purchase a 9650 - stores won't tell you
the stepping, which is why AMD changed the model number to
indicate a fixed part. Stores advertise product based on
the processor model number, so 9650 makes it easier to find
a fixed one.

So in essence, they had a serious problem with the Phenom processor,
earlier in the year, that affected the processor stability... SO they
fixed it for the
models, and then put 50 at the end to indicate it's a fixed processor
and running
with all L caches stable. Thanks for clearing that up. :)
