Its very unlikely, you would probably need a new motherboard.
I fail to see however why you think your processor is redundant. Is there a game you wish to play that your PC won't run is that what concerns you. I have a 3500 AMD chip, just a bit faster than yours and my mate has a 2500 AMD chip and although they aren't the fastest things out I wouldn't consider them redundant.
A new graphics card might improve things.
