I have this old computer and I want to upgrade from a Pentium Dual Core E5800 to a Dual Core E8400, I know they need the same socket (LGA 775) but i was wondering if my bios version would be compatible, my bios it's an Inspiron 560 but 12/01/2010 version, I went to dell.com and theres an update, that's why I was wondering if it would be compatible,
Here's what I found online
