I've got 6 GB of DDR3 Ram in my system, in the order 4+2, and I like to game on it. Earlier it was 4GB, 2+2 which happens to be the Minimum Requirement for GTA-5, however the game would start lagging right after 2-5 minutes, although I have a dedicated Video card and a monitor of 1366x768 Resolution? So I had to upgrade the Samsung with Ripjaws x to make it 4+2. Now the Game runs alright at 60 fps with Normal settings. But I doubt whether 6 GB would be okay for Watch Dogs -1 and 2 with the Min req of 6 and 8 GB ??
