I have a dell Latitude D610 with intel centrino model processor witch is 1.6ghz and I was wonder how much it would cost to change the processor to 2ghz cause I read I can change the processor to 2ghz centrino let me knowI have a dell Latitude D610 with intel centrino model processor witch is 1.6ghz?I don't think you can upgrade centrinos because they don't just sell them by themselves. Theres no point in upgrading a laptop unless its RAM or HDD. If you are looking into upgrading the CPU, just get a new computer.I have a dell Latitude D610 with intel centrino model processor witch is 1.6ghz?You'll get more of a performance boost by increasing the memory. The difference between the two processors is negligible in most applications.
