I'm looking to upgrade my GPU, and trying to understand the differences between memory size and clock speed and how they affect performance. I use one monitor for gaming. I plan to play the new FIFA and hopefully GTA V, but also want to do some graphics modding on Skyrim, which I understand can be affected by memory size more than clock speed, but I'm not positive.
For example, I've been looking at the GTX 580 with 1.5gb VRAM and 4008MHz memory clock speed. How would that card stack up against a card with say 3 or 4gb VRAM but with a much lower clock speed? In general, what matters more?
