Hmm... You should be using Windows 7 64bit. I
presume if u have bought an upgrade DVD, it is automatically
included 2 copies and no refund from your store is required. If you
buy a brand new PC and upgraded it to 8GB RAM then ho seh liao.
BTW, why are you using integrated graphics, for a viewpoint of a
professional media works? Since you are using integrated graphicsas
below source from u
Then you will still using like 7GB or 6.5GB of RAM after you
have changed to 64bit version of Windows. (Windows 7 64 bit)
I doubt he has integrated graphics.
He has 1024MB of video memory, indicating a 1GB framebuffer on
his GPU. The shared system memory may be due to technologies like
AMD HyperMemory or Nvidia TurboCache using up system memory to
increase the amount of framebuffer available for programs to
use.
