I am running Windows 7 Ultimate SP1 on a machine with an Intel i7 CPU 920 @ 2.67 GHz. The graphics display adapter is a NVIDIA GeForce 570. I noticed the other day when I was looking up something in the System area of the control panel that the installed memory was only showing 4.99GB out of 6.00GB as usable. This was not the case when I first purchased the machine. I upgraded to the 570 a year and a half ago.
