1. 8GB = RAM + Video RAM. A game that "only uses 4GB of RAM" on a PC will also be using 2GB of Video RAM easy
2. Using more RAM is very easy to do, helps you not have to load stuff from the slow hard-drive, and costs nothing. All games should use all of the RAM available or they're being inefficient.
3. Conversely, more RAM does not by itself equal faster.
