I have an Inspiron 560 with a Core2 duo E7500.  Motherboard is 0K83V0.  I came into possession of a working Core2 Extreme QX9770 processor.  I'm wondering if it's compatible with my motherboard (I know they're both Socket 775LGA).  Bios version is A06.

So I'm left with 2 questions...is this processor compatible with my board and BIOS version?  And would this cpu need additional cooling over the stock dell fan?

Thanks for your help!
