So I think I've narrowed it down to two computers. As far as I can tell, the cheaper one is identical to the more expensive one except for the graphics card (or I may have missed something, entirely likely)

will I regret getting the lesser computer? is this a good price for the parts? which one is a better deal?

the computer will be used for playing games, so will they work for that?
