Question: what is the difference between 2gb graphics card and 4gb?
Answer: Dignified. the difference is how much ram the card can pull from so in games that are optimized poorly the card with the more ram will have more to pull from. I have seen a 960 use 3700mb so having 4gb is not out of the question. But a 2gb card will be fine 90% of the time where it wont matter.
