I have a Dell Inspiron 1420 laptop with the Intel Core 2 Duo T8300 2.40GHz processor in it. I want to upgrade the CPU. I have shortlisted two CPU from which I need to select anyone. The shortlisted CPUís are T9500 (2.60 GHz) CPU or the T9600 (2.80GHz) CPU. But the issue is I am not able to decide which one to select. I have the latest BIOS (A10) on my Inspiron 1420. Can anyone help me to overcome this issue? I donít know which one is better. Please do the needful if you can.
