I have an IBM thinkpad and I want to upgrade the video card. Im no computer expert so I dont even know if this is possible or not. I talked to people and they say get GeForce or ATI radeon, and before I get one of those video cards, I want to make sure there is actually a version of these that I can install on a laptop, or if a PC video card is compatible with a laptop. Can anyone assist me with this issue?
