Yes, but you could OC 650M to have similarly with 660M i think

I just can't answer that question, because I have no experience directly with the $1299 model. It wasn't a choice I made, my lovely wife got it for me, and she probably knows me well enough that I usually never buy the base model of anything (and when she ordered it, the 27" wasn't available for XMas).

Hope that puts it in context.

Now, THIS interests me. But only if I could do it in OSX (I have no desire to install Windows on this lady.

So i tested both of them 640m and 650m stock (No OC).
On high demanding games like Farcry3, witcher 2 etc on native resolution the differences are:

around 40-60fps on 640M with everything medium+high(no AA)
around 50-60 fps on 650M with everything to high+ultra (no AA)

So not much difference between the 640M and 650M for a layman gamer then?
I'm the layman

it is a difference but ..overall the base imac model it is a powerful machine but a little help from fusion drive will be a must.
When you run an app will be faster thnx to fusion drive, when you run graphic will run smoother thnx to the 640M, and the quad core i5 processors are indeed a power house.. i think this machine don't need 8 GB RAM, with 4 should be more that enough

I would call that a substantial difference. I didn't expect that much of an increase in fps AND detail.

I just found a new benchmark to test OpenCL (not GL) Luxmark that I learned of at barefeats.

I ran the GPU only test and scored 267 rendering the Sala scene.

Can you tell me specifically how much FPS you get playing Witcher 2 on 650M with high/ultra settings?

I'm going to make an assumption here on Serban's behalf (at least until he corrects me), and that is this: since he listed Far Cry and Witcher 2 together, I'm guessing he's running them both in Bootcamp.

Performance for Windows games in Bootcamp will be better than on OSX, at least until Apple updates OpenGL to version 4, and we get performance and graphical tweaks (like hardware tessellation), which OpenGL 3.2 doesn't support.

Yes, only boot camp
