first, what is the difference between a video card and a graphics card
second, I bought this computer on 6/12/13 but i need to upgrade my video card i think... im trying to play sim city but i cant with my video card (EA help told me its the video card) i have Intel HD graphics 4000 and NVIDIA GeForce GTX 660M
can i upgrade it or get an external?
EA tends to do that as an excuse for them to not fix things. For me they've told me I cant use Win. 8. Your graphics card is decent enough for sure, and upgrading will not change their support of it necessarily (meaning the game might not support 700 series mobile chips). In addition, Video cards and graphics cards are the same thing, they are responsible for processing the visuals of games and rendering in supported video editors. As for external options, Vidocks seem to be among the best options, from places like http://www.villageinstruments.com/tiki-index.php?page=S... . Finally, as for an internal upgrade, I believe your card is soldered in place and is not replaceable by the user.
your problem is that the laptop uses the intel video card , thats why the games doesnt work good , the nvidia gtx660m is very strong card .
there is a combination (Fn + F7 i think , to switch off the intel card and to use the GTX only , then the games are going to work greaT
