This reply here is totally my opinion . Further to this , you are unlikely to ever need much more than 550 w unless you decide to SLICrossfire as components are actually starting to draw less power from the wall , just check the power consumption of the latest intel processors ! <| sep |> There were a number of the reviews that made it seem like it would be next to impossible to finish the game without killing someone at some point . In addition to that the reviews made it appear that stealth was a tricky element of the game that did not feel as well as it should have . Story is a big factor here for me and that is why I continue to hold off on the game based on what I have seen without spoilers . This is the first time , in all honesty , that I have heard a comment related to the game that indicates that the player completed the game without being directly the cause of multiple deaths .
