I have a limited income for a new computer, and I am primarily relying on the sale of my laptop. I don't have much experience choosing new desktops. But bellow are a couple choices I have. If anyone has any suggestion it would be greatly appreciated. I have a ps3 but really like the mods for Fallout 3 and would like to get a desktop that can run it as good as the ps3. 1st is a Asus http://www.bestbuy.com/site/Asus+-+Factory...p;skuId=9721104 2nd is a Hp http://www.bestbuy.com/site/HP+-+Factory-R...p;skuId=9720872 Also is there a significant difference between 2core dual and i7?
