I have Touchsmart all-in-one model 23-d027c which contains "HD graphics 2500" which I now realize means "don't even try to use it for games". I'm wondering rather than throw this machine in a lake is it possible to upgrade the graphics card? What card would possibly fit in this thing? I see one for sale with a NVIDIA GeForce GT 630M which would be better but is still wimpy. I'm wondering what's the best card I could cram into there. My instinct is to donate this to the library and buy a plain old box with a big fat graphics card in it, but I'm curious if this all-in-one is salvageable.
