I just purchased a new computer, the Sony VAIO L Series Black All-In-One Touch Screen Desktop Computer - VPCL213FX/B. I was curious if it was possible to upgrade the video card in it since it seems more like a really big laptop then a Desktop. The computer has a Intel® HD Graphics card in it. Could I put a gaming video card in it and play games a little better? The higher models come with the NVIDIA® GeForce® GT 540M. Thank you for the help!
