I find it amazing how useable Core 2 computers remain, even in this day and age.
I have
- Two Core 2 duo DDR2 machines
- Two Core 2 quad DDR3 machines
all of which run Windows 10 well
The limitations are CPU instruction sets. The C2D/C2Q line just don't have many of the newer, well utilized, features. Even 1366 gen CPU's are lacking a few, such as AVX. While OS software will run, there will be an increasing number of software titles and games that do not.
Will the Dell BIOS support a Core 2 quad?
Yes, that system supports all of C2Q range except maybe the Extreme range, not sure about those. The G33 chipset was an economy/budget offering for the last gen of 775 CPU's and was design to support the Quad range or CPU's.
Just Google it - Sad but Meh

The user "Speedstep" needs to be ignored. The limitations that user described are complete nonsense. There are plenty of G33 based systems that fully support Quads that only have 3 phase power, to no ill effect. The logic and reasoning he presented are deeply flawed and flat out wrong. ALL versions of the G33 chipset will support Quad core CPU's. However, the "Extreme Edition" CPU's are an area of concern, but that is the ONLY concern. A concern negated buy an upgrade of PSU to a 350w or better.
