[SOLVED] Can I Upgrade by Core 2 Duo E8400 TO Core 2 Quad Q9650

[ICY11]

I Have an HP Compaq DC7800 Compatible Minitower with an Intel Core 2 Duo E8400 Installed, I was Planing on Upgrading it to Core 2 Quad Q9650 for better performance, here are my PC Specs:

Mobo: HP 0aach (Intel q35 Chipset)
Ram: 8GB DDR2 Ram @ 800Mhz
Graphics Card: Nvidia Geforce 8400gs
PSU: 365W HP (IDK the Efficiency)
O.S: Windows 10 Pro 64bit
Bios: v1.35 (according to many youtube videos, this seems to be the latest one I can install)

Note: If not compatible then please do recommend me some Other 4 core CPUs I can fit in, or If I can Put another CPU More Powerful than the Q9650 Please do Recommend me those as well. Thanks in Advance.

The q9650 and every other quad core processor should work:
