Just my opinion here, I've built hundreds of computers over the years and just upgrading the CPU while keeping the motherboard is a bleeding waste of time and money.
You're gonna have to make a checklist first or it could all blow up in your face.
Just for starters.
How old is the PC, if its too old its pointless.
How much Megahertz will you get after the upgrade and how much will it cost, bang for your bucks matey that's the name of the game.
Will your present cooler cope with the new CPU, if not you'll fry it.
Keep the same CPU chip type, even if its more expensive, you cannot put an AMD CPU into an Intel motherboard and vice versa .
You are upgrading a CPU which is hardware which doesn't come with any windows software programs as they are already on your SSD or Hard Drive.
You're looking at this as though you're buying a new ironing board matey, its more complicated than that.
