I purchased a new computer and the desktop has a * 512 (MB) NVIDIA G310 GeForce® video card. It doesn't have an HDMI interface but DVI, I'm not sure if ones better than the other. I'm wondering if I should upgrade the video card. I'll be running windows 7 and Ubuntu but the thing is I won't be doing any gaming on the computer other than casual gaming. I have a play station 3 that I do gaming on. Would there be a need or would I notice a difference if I updated the graphics card for everyday and multimedia computing? Do I want to have a card that runs thru PCI Express 2.0 x16?
