I'd personally get the 2gb version if your only planning 1080p and a single card. 4gb isn't really needed as it would run out of Gpu power before the 2gb is used up. It would come in handy for SLI if you plan it. If it's like £10 more for 4gb vs 2gb get the 4gb but if it is quite a bit more I'd get the 2gb.

The 680 is capable of running games like Shadow of Mordor on high textures. At 1080p, that game takes around 3gb vram.
The gtx 680 would struggle a constant 60fps on shadow of mordor at 1080p. it also uses around 2gb at 1080p not 3.
Monolith recommends a 6GB GPU for the highest possible quality level - and we found that at both 1080p and 2560x1440 resolutions, the game's art ate up between 5.4 to 5.6GB of onboard GDDR5. Meanwhile, the high setting utilises 2.8GB to 3GB, while medium is designed for the majority of gaming GPUs out there, occupying around 1.8GB of video RAM.
Nope.
What that is saying, is unless you like low textures, 30FPS or stuttering you need more than 2GB. http://www.eurogamer.net/articles/digitalfoundry-2014-eyes-on-with-pc-shadow-of-mordors-6gb-textures
On PC, memory is typically split between system DDR3, and the graphics card's onboard GDDR5. Running high or ultra graphics on a 2GB card sees artwork swapping between the two memory pools, creating stutter.
The gtx 680 wouldnt use over 2gb for a comfortable playable experience at 60fps on very high settings 1080p.
It will use more vram because a 6gb card has the capacity to do so, doesnt necessarily mean it will perform better than a more powerful 4gb card. GTX 980 SLI at 4k maxed settings with shadow of mordor still uses less than 4gb vram its close to its full capacity but still doesnt use over 4gb at 4k maximum settings.
Maybe you should look at some gameplay for the 680 on mordor then maxed out it uses just under 2gb with 99% usage. I'm not saying it wouldn't perform better but there would be marginal difference between the 2gb and 4gb unless it's in SLI if it was €10 more then it would be worth it.
It's like the r9 290x 4gb vs 8gb. Unless it's in 3-4 crossfire it makes minimal difference.
