Just like Dell puts it like 1 to 2 years ago. The GOOD system configuration for Windows Vista of 512MB of RAM is ideal for booting the operating system with no programs or games running. The same can be said in a windows XP box with 96MB or RAM, it would barely be enough to boot up XP but if you try to run any other software performance will suffer due to lots of virtual ram activity. for Windows vista and windows 7, we still do not know what constitute "enogh ram" and "plenty of surplus" for them, since any ram you stick on these machines, windos 7 and windows vista will eventually end up consumming the mayority of it, and eventually will start using paging files (virtual ram) when there is not enough ram for "caching lots of progras" i the background. Hear this: In an attempt of vista and 7 in improving user quality experience by caching everything these OS thinks the user will be running in the future, it, inadvertently makes the system slow, and sluggish, eventually all of your 4 8 or even 12 GB of RAM will get ran out, and you all know what paging file does to your system.
is there any way to disable that "caching" feature, (super fetch), I never needed it in all the operating systems that I have used, and I certainly do NOT need it now, and much less forced upon me by Microsoft.
