Acer is good company. You can't upgrade because youc an't stick in any card. Even pci-express ones, it's hard to upgrade, as you have to track down sellers of them, which are usually oems. Yours isn't pci-express, frankly i have no idea what gfx card is even compatible with the notebook. Notebooks are not upgradeable, except ram, hard drive, and optical drives, or at least for most people. Pretty sure, you can't upgrade anything as you have no upgrade possiblities with the integrated gfx. if you're wondering why i'm probably the only one replying, because this thread is a waste of time...
