Summary: I went from a 2.20GHz Dual Core Pentium to this 2.80GHz Intel Core 2 Duo. I haven't had much time to test it yet but I am going to install some Steam games soon and test it out. I'm not sure if my old Pentium was a bottleneck with my XFX AMD Radeon HD 5450 1GB.
Summary: I bought this in 2009, it was released in 2008. I am writing this in 2014. So I 've had it for 5 years. I have never had a problem with this chip. Even now I am hesitating to get a new chip / MBoard / RAM combo, as this does the job good enough.
