We really don't know what demand the game will put on VRAM yet, so I'm not sure dismissing 2GB as inadequate isn't premature. We really need more information on resource requirements, and trying to nail these down while the crew is heads-down trying to do optimization is difficult.
I don't think I dismissed 2GB as inadequate, I only said it might be problematic. I came to this based on the performance of other large open/semi-open world games like the Witcher 3. AC Unity, Dying Light, and Dragon Age Inquisition for instance..
I've noticed that recent DX11 games have a tendency to use as much VRAM as possible for caching textures, shaders etcetera.. And thats a good idea, because it reduces memory management overhead significantly.. But the flipside is of course, that VRAM is more important than ever..
If the Red Engine 3 is well programmed for PC architecture though, it's conceivable that 2GB may be completely fine. Theoretically speaking, a 2GB GTX 680 should still be able to use the highest quality textures, because on PC, the textures reside in both VRAM and system memory and most gaming PCs have at least 6GB to 8GB of RAM these days..
So even if the 2GB of VRAM isn't enough, the system RAM will buffer it and swap in textures on a need basis. But of course, some engines are more efficient at this process than others. From my experience, CryEngine is extremely efficient at memory management, and so is Frostbite 3. Unreal Engine 3 can also be very good, depending on implementation..
The worst engines for PC are made by Ubisoft. The Disrupt Engine used in Watch Dogs was absolutely terrible, and whilst the AnvilNext engine used in AC Unity is far superior to the Disrupt Engine, it's not in the same class as the elite tier from CryTech, Dice and Epic..
I have faith in CDPR, that their Red Engine 3 will be optimized very well for PC memory architecture, as they're primarily a PC developer unlike Ubisoft which focuses on consoles.

are 2GB VRAM =(, i hope you have not reason xD, i can´t wait to may 19 really i want to test this game right now!
i have a i5 3570k to 4.5ghz overclocked i hope this one helpme a bit =P
CPU wise, you're definitely good
