Summary: I was really impressed with the processor speed improvement. I had the Intel Core 2Duo E7300 2.66Ghz. I also went to the next Intel Xeon X3360 2.83Ghz and that really my best performance and screams.
Summary: I ordered this CPU as an upgrade from my older dual core celeron. It arrived on time and in complete working order. unlike the last time I order a similar chip from a different company. Awesome!
