I would like to upgrade my older desktop just enough to play Sims 4. I have a Dell E520 with windows xp. it has two 512mb memory cards about a 100gb harddrive. i belive it has an intel g965 processor. besides that i'm not too sure what else it has. But basically i would like to upgrade it, fairly cheaply, enough to play The Sims 4. Any help would be greatly appreciated
