PS don't buy a computer just to run one game, think about how it's going to last you, how long the life of it will be, what else it can run, because in about a year or whatever, you'll be bored of Minecraft. You need a computer that is going to be used for other things. I mean, you could run minecraft with a good 40FPS on a ruddy netbook, one of those tiny things, so if anything, buy a computer for the specs so that you can run everything else, not just minecraft.
