which is better? a 3gb of ram and a 1gb of vram vs 2gb of ram and a 2gb of vram?

Solution
VRAM is not related to the RAM. VRAM only pertains to the graphics card whereas RAM is for the system and its requirements (to put in easy way).

Now a days, 2GB VRAM is like a must requirement with modern games requiring more than 3GB of VRAM. Also for System better consider 4GB RAM as minimum.
