would this cpu be compatible??

[fez1200]

mobo is intel DQ45CB
4x 2GB DDR2 PC2 6400
current cpu is intel core 2 quad Q8300 2.5ghz.
i was wanting to know if an intel core 2 extreme QX6850 quad core 3ghz 1333mhz 8mb cpu would be compatible as a plug n play swap.
cheers guys.

The QX6850 is not listed as being compatible for that motherboard, so probably not: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/desktop-boards/DQ45CB.pdf
