Dell optiplex 3040

Solution
The i5 6500 is a far better chip. Both are based on the same architecture, but the i5 is clocked 100mhz higher but has 4 cores instead of 2 cores + HT, and 6mb of cache instead of 3mb.
Possibly, but I'm not sure why you'd want to. I don't think the 3040 ships with anything less than an i5, so the Pentium would be a huge downgrade?

EDIT: I'm fairly certain it has a 1xx chipset, maybe H110, so it should support 7th gen chips such as the Pentium so long as Dell has provided an updated BIOS that adds support for them.
 
I already check from dell website . Its support 6gent cpu .

My bro doesnt want to use it anymore . So he gave it to me . I want to use i5 6500 in my gaming rig . So i want swap my g4560 with i5 6500 . And sell the dell pc to upgrade my rig . Do u prefer g4560 or i5 6500 for my gaming rig ?
