How good would the AMD Radeon HD 7450 go on minecraft. FPS ?
It will get you 60fps required for smooth gameplay anyway I'd say.
Again MexicanTurkey, it will run fine on that desktop you just linked and that video card. Minecraft isn't a demanding game at all, you could play it on a pay as you go phone haha ;)
Maybe even a Nokia 3310
should run it OK
its should run ok, but on lowest or low settings.
