Granted there is a lot of information for and against pagefiles, I did not think completely turning off the pagefile was a wise choice regardless of how much memory you have installed. The only tweak to pagefile I make is to move it off my OS drive and onto a secondary data drive. I could be wrong. There is a lot of articles saying do this or do that, but if you're happy with performance, then I guess stick with what you have setup.8GB
And if 8GB wasn't enough I do believe my machine would crash, because I have my Pagefile turned off. Until I run into problems with lack of memory, I'm not worried about having more.
