Which iMac for playing GTA 5?

[NbinHD]

What is the cheapest iMac that should be able to run GTA V/GTA 5? I want around 30 fps, which i believe is playable and fine for me. GTA will be the only game i play.

I can't answer your question, but you should keep in mind how long you want to to keep the Mac for and what games you might be playing before you replace it.

For example for someone who plays games and will be keeping the Mac for 3 to 5 years, I would suggest the 27" with the 680MX. If you're the type to replace your system every year then go with the minimum system needed.

It depends what settings you'd be running the game on, if you're happy with medium and lower settings then I think the 650M in the 21 inch would be able to handle this at 20-30fps.
I'd highly recommend going with the 27 inch with the 680MX, as this will last for many years, and you'll be able to run the game on high settings at native res with 40+ fps I'd guess
