A few things:
Here are the requirements for Media Composer, as of this morning:
https://www.avid.com/US/products/Media-Composer-Software/system-requirements
As you can see, your Intel Core 2 Duo meets the minimum spec.
What you DON’T have…
Ample storage for lengthy 3D material (remember, your storage will have to house the RAW footage- L&R eyes- plus the MUX, plus renders and misc stuff)
A way to view 3D on a 3D monitor. You’ll need a Mojo DX, Nitris DX, or a Matrox MXO2 Mini to view the 3D Video output. The iMac does not have provisions for the host card (pcie slot expandability) that each devices needs.
You’ll also need a PC in order to use Metafuze, which is the part of the Avid “sanctioned” 3D workflow (this free app takes L&R eye files, muxes them into 1 file, so Avid can use it). This, of course, goes on the assumption you use Avid’s workflow and not Cineform’s Neo3D workflow, which will cost you another $3000.
I’d read up on the Avid 3D workflow: https://www.avid.com/US/industries/workflow/Stereoscopic-3D as well as check out the stereoscopic forum here on the ‘COW.
Good Luck.
