If you want to play the game, it is. It's like that, no matter if it's a console port or not. Besides, it's an open world game, it uses lots of RAM if you want it to look good. Next year GTA V will be released. It will probably take advantage of Radeons HD6950 and 6970 2GB, which, by then, will be one year old cards.
With your comment you didn't even address the long-term question. The OP clearly said he wanted those cards to last more than 3 years. No way that is going to happen with 1GB of VRAM.

If you were using a much larger resolution, you would be able to enjoy the eye-candy even more with those settings you are currently using @ 1680x1050. 2gb VRAM is more beneficial to resolutions larger than 1680x1050. There's nothing wrong having 2gb of vram for 1680x1050 but at the end of the day, difference is very, very minimal. You do not need 2gb of vram for 1680x1050.
I don't need more performance; the GTX480 is able to handle the load just fine.
The question you are continuously overlooking is: you may not need 2GB of VRAM for 1680x1050 NOW, but you WILL in the FUTURE. Isn't that your goal ? Didn't I quote you saying that ? It's easy to guess what kind of VRAM you will be needing, even at 1680x1050 in two years.
And with Full HD monitors so cheap, are you sure you won't be switching monitors faster than GPU's ? Say, in a year, a year and a half ? I will. I will be buying a Full HD monitor in a few months' time.

OP: Let me just also say ... if the plan is definitely to go SLI with the card you buy, and you for sure want to future-proof your setup ... I'd get the 560 2GB version. I concur with TPI on this point, given that just because you're at 1680x1050 doesn't mean you always will be, and vram usage is just going up over time.
If you know for sure you're sticking w/single card though I wouldn't bother with 2GB because the single 560 gpu is not really powerful enough to push apps at settings that require more than 1GB of vram. Two of them will, though so the 2gb option makes sense for 560's in SLI.
I didn't measure it, but I can. Meanwhile, I took a screenshot of GPU-Z while Metro 2033 was on, 1680x1050, Very High Settings, Advanced PhysX off.
Here it is:
