Depend if you wanna run with or without mods. I have a Dell XPS 8500 and it runs minecraft on maximum setting with multiple high end mods. some of the specs are as follows.

Windows 7 Home Premium.

12 GB of RAM installed

i-7 3770 @ 3.40 GHz

64-bit operation system

AMD ATI Radeon 7570 Graphics Card(Nvidia is better btw but Radeon is cheaper)

i also did some tweaks so that my games run smoother

It cost me $950.00 tax not included

Nope, all Dell computers are exactly the same, and not like any other computers, and none will run good with Minecraft, because Dell.
