Not only the chips are the problem, that board still uses ddrI memory instead of ddrII.
I'd suggest you try to sell those parts you don't need anymore, get a new Mobo, processor and graphic card the rest might be up to date still (sata hdd's?/dvd?) I'd get some black dvd drives, they would look a lot better....
My system a s939 amd X2 3800, geforce 7600 GT silent, 2 dvd/rw's 2x 500 gig hdd raid 0 was sold for 400
