How can I see how much RAM my videocard has in Windows 7 ?
If it's like Vista then you need to navigate to "Control Panel", "Performance Information and Tools" then click "View and Print details"
Update: yes it's the same on my Win 7 netbook. You might need to change Control Panel's view to "small icons" to easily find "performance Information and Tools".
the easiest way is to use the DirectX Diagnostic tool.
into the search field in the start menu.
dxdiag should come up as an option. run the program and view the "Display" tab.
the display tab provids information on your video card.
there is a line named "Approx. Total Memory:" this line holds the ram on your video card.
