i currently have a Dell computer i bought around 2005-2006. i want to switch to a faster processor than what i have. Pentium D 805 95nm 2.66Ghz 533 FSB. i tried a core 2 E7200 but my system didnt start. im looking into pentium dual core processors but theyre all manufactured in 45nm technology. would i be able to use those or do i have to look for another 95nm pentium processor for my system to function???
