hey
well if u got the money go here boxx
best around latest 1 is 4 dual core procews ors with 64gig ram 7.5 trrabytes hard dive space but its pricey but they have cheaper 1s

i would personally build a pc its much cheaper and u get good specs my lats was areound 700-1000£ cheaper by building it ull propbly find actual os is most expensive also oing iy=t this way it will be easier to upgrade in years to come as u wll know what it can/cant handle

but make sure u get at least a couple gigs of ram it is a must

a decent pc will last a few yrs but remem no pc will state state of the art as new parts come out all the time making it impossible to have the best

but mainly go with what you can afford
