Single 1GB Card or Two 512MB Cards?

Would a single 1GB card give me the same results as two 512MB cards?

Just thinking that two cards mean more cores and more processing power?

Any thoughts?

  1. You have to mention what cards specifically you are talking about - vram amount by itself means nothing.
  2. vram is largely irrelevant to performance.
    Here is one example study of 2gb vs. 4gb :

    Also, when you use two cards the vram is not additive.
    Lastly, two cards, particularly lower powered cards may exhibit microstuttering.
