Getting Computer Information

Well, more specifically, is there a way to return the amount of memory that an End User's Graphics Card has using Windows API's?

I need it for bug reporting purposes in my program which uses several different themes that might require a certain level of graphics card. Is something like this possible in any way, or am I going to have to use WMI..which I really want to avoid.

I only know two ways:
1 - WMI
2 - DirectX

To use DirectX you need the SDK, and need to import the namespaces... so if you already know how to get that info with WMI you should use it...

Like Mickey said, you can use wmi to query the Win32_VideoController class to get that information.
