dedicated memory GPU

Hi all,

just got my new laptop (xps 15z). The specs said that it should come with the Nvidia GT525M 2GB graphics with Optimus but it does with the 1GB version. I have used dxdiag and sys information and both say that, indeed, this is the 1GB version. I would like to triple check this property before sending it back to Dell. Is there any tool you would recommend in order to figure out the properties of the GPU? Thanks, D
