Hi, I am looking for a new CPU but can't decide which is proper for my MB. I got confused with AMD's sockets. AM2, AM2+, AM3 what is the difference between them. When checking the Gigabyte's website I can't find AM3 ready logo near specifications for my MB anymore although it used to have one earlyer. So if I bought any AM3 CPU on the market today and probably in the near future will it work without any downgrades or limitations?
