Why do you want to make a change?

Reason: problems, performance, future growth?

Update your post to include full system hardware specs and OS information.

PSU: make, model, wattage, age, condition (original to build, new, used, refurbished)?

Disk drive(s): make, model, capacity, how full?

Attached peripherals?

Thread seems to be in the wrong section.

Listing all your hardware would be a good place to start. If you are on a 3xx chipset motherboard you may or may not have BIOS updates to go that far later (CPU).
