(Sorry I listed wrong models in the title!)

I'm just wondering how big of a difference there is with the graphics card options in the two 27" iMac models. The cheaper 27" comes equipped with a GeForce GT 755M 1GB, whereas the dearer one can be upgraded to a GeForce GTX 780M 4GB. So:

GeForce GT 755M 1GB
vs
GeForce GTX 780M 4GB

One thing I do a lot of is working with 3D space in Motion 5 and in the past my projects can start to get very laggy. I'm guessing the additional 3GB in the 780M will be able to keep my projects running smoother for much longer? Or will the difference really not be that noticeable?

I can save a lot of money going with the cheaper 27" iMac, but if the fully upgraded graphics card will make a world of difference for Motion projects and a few games on Bootcamp, then I think it'd be worth it. How different do you think the two iMacs will perform?

Thanks for any help. :)
