This is based on the research I did with optimizing my machine for graphics. I also wrote the following article: http://www.paradoxuncreated.com/articles/Millennium/Millennium.html It is a bit outdated now, but I will update it with current information. The value might iterate.
Peace Be With You, Uwaysi Bin Kareem.
