Can somebody please explain to me the pros and cons of a graphics card and its ram allocation i.e. a Titan has 6GB and a 780 has 3GB and they perform very similarly in benchmarks. So, what exactly is the benefit of more more ram?
More VRAM is beneficial is you are running high resolutions such as 3 displays since nvidia only supports 1 or 3 when gaming. If you are playing in 1 screen the VRAM shouldn't make any noticeable difference.
