I bought Dell Inspiron 15r -5521 with i7-750GB HDD-8GB Ram.
abutareq@P-Box:~$ sudo lshw -businfo | grep -i display
pci@0000:01:00.0 display Mars [Radeon HD 8730M]
pci@0000:00:02.0 display 3rd Gen Core processor Graphics Controller
Steam keeps telling me when I change the display that I have only 250 MB video memory.
I removed windows and installed Ubuntu 13.10 because I want to use windows on Vmware and I read about enabling 3d in VM but my device does not support 3d, that's what Vmware says.
