Desktop AMD Phenom II x 4 vs. Intel Core i5?

I suggest you to go for #3 because when we are desided to buy a machine we are considering 4 magor parts Processor, Ram, VGA card and Hard Disk so as your requrment amoung the three machine the last one has got a Good VGA card so it's performing well for the Videos and Gamming so better you go for a Last Machine...
