My Computer has a Pentium Dual Core 2.2 ghz cpu in it.It seems fine and everything.However im intrested in upgrading it in the future.I know my motherboard is a socket 775.Will any socket 775 cpu fit in my motherboard?Are they just plug and play?I have installed one before on a old pentium 1 computer and im pretty sure that was just plug and play.Any help would be appreciated...The computer i have is a dell 530s so its not the most upgradeable unit.However im still intrested in it.Thanks
