Yeah thanks I understand the model similiarities. Just I've ordered mine from the states and it comes with the option of choosing the GTX 680M 4,096MB PCI-Express GDDR5 DX11 on Clevo P379EM or the SLi ENABLED DUAL (2) 4096MB PCI-Express nVIDIA GTX 680M's (8192MB which is $900(too much for me for time being)
