I'm buying my daughter a new computer. I have limited money so I'm thinking referbished. I have a couple of Dells. Both choices have AMD Athlon processors. One is 64 Duel Core, the other is x2 processor. I'm not sure if one is better or both the same. I learned a lot from reading the forum on this sight but I'm still a litttle confused. Both of the computers have integrated nvidia Quadro nvs 210s graphics. She mainly uses it for internet (UTube video) and Sims. She plays sims 2, and just got Sims 3 but her old computer is not capable. Sims 3 requirements name many nvidia Ge Force, Radian (several) and intel GMA 3 & 4 series. The Quadro is not included, is that because it's to new or because Quadro is actually for business application?
