More VRAM allows your computer to load more and higher resolution textures or 3D meshes onto your GPU, as well as render images at higher resolutions (multiple monitors is the same as having a higher resolution).

When your GPU does not feature enough VRAM, it will load its ressources onto the system RAM instead. However, due to the system RAM's distance to the GPU, it is a lot slower than VRAM.

If your GPU's VRAM is full during a game, chances are that you might see your FPS boosted a lot by upgrading your GPU's RAM (which is unfortunately not possible, since VRAM is soldered onto the graphics card)

Id say that it doesnt make any difference for a GTX 850 because it isnt fast enough to play games at settings where they need 4 GB VRAM.
In video editing and stuff like that it may be another story but i dont know much about that.
So if you're just going to play games go for the (probably cheaper) 2gb version.

You definitely want to get the GDDR 5 version. GDDR5 is many times faster than DDR3 and that is why it is more expensive. The GTX 850 can saturate more than 2 GBs of vRAM but only if it can get it fast enough and the DDR3 is just too slow.

For now 2 GBs of GDDR5 is a good spot. You can't be playing with maximum settings, but you still will have a pleasant experience.
