If you are a home user and you will not use Final Cut Pro, Photoshop or Aperture for serious work, leave the included GPU. You do not need the upgraded GPU because you will probably not experience any difference.
The difference may come with 1080p or even 4K videos in Final Cut Pro X and 3D rendering. Here's where you will experience better performance, even if it is a little only

With iMacs, like notebook computers, you cannot upgrade much of anything once you buy. So give your current AND future needs a good review before making a decision.

I take your point about future needs, but at the same time, if the 2GB card was the top end just a year ago, then I wonder if the faster card makes a real difference at all.
Mende1, I'm saying that I will be using all those apps snf I'm using them all for my work, so seroius work, but can't ever imagine editing 4k video and no 3d rendering. I will edit in 1920 HD though.

You need an experience from an user who has got that GPU to determine that. Anyway, you can be sure you will get better performance with that upgraded GPU even if it is small (this is the reason why you need a real experience), and what it is more important, your iMac may be useful for you for more years, an important thing in your case

I think anyone with the better GPU will say that it's great. What would be more interesting would be someone with the GPU 775 who uses it heavily. Does that person feel it's underpowered? Do they wish they had a more powerful GPU? So far, I know someone with an early 2013 iMac and they have no issues with editing or Photoshop and that GPU is an older, 2GB card.
