What will run on this?

I'm sorry to tell you but Minesweeper won't work unless you're using the lowest graphics. :

OK, enough of joking...

I guess you should try to search on YouTube for videos about the graphics card you're going to use and the games you wan't to see how they'll work with it. There's tons of such gameplay videos... Almost in all of them is listed the other computer specs as well, so you can see how much it relates to your own computer.
