I am currently using a 5400 BE OC'ed to 3.2Ghz stable, but want to upgrade due to a bottleneck.
My choices are
Phenom 9500 2.2Ghz, (but figured out its not that great a buy)
or
AMD Phenom II X2 550
The second option supposedly will work better for gaming, + I could OC it to 3.8 ish Ghz. It also has a significantly higher cache. For gaming (which want) it is obviously the better choice.
