Hi all ..I am new here I wanna ask about your opinions on this Should i get Amd Phenom x2 555 or Athlon x4 640? the pc is for gaming mainly. but i want to run quite well on simple multi-tasking as well like for example: playing game while ripping dvd or while scanning pc or ripping dvd and scanning pc while browsing the internet. i read that if its only gaming, phenom x2 555 would perform better. and im happy with that but can it handle the multi-tasking i mention before?
