Upgrading my old computer?

Check these parts out at Newegg.com. I just got a new mobo from AS Rock AM3 for $60 at Newegg.com and 4GB ddr3 ram 1600 for $40. and an AMD processor Item number N82E16819103871 Athlon IIX4 640 Propus 3.0GHz Quadcore for $99.99.. I buy my parts at Newegg.com as they are equal to Amazon or better. You can use the same hard drive unless it's really old. Just reinstall Windows on it and all the junk files will be gone and you will have lots of free space. Save your pics and music first as all extras will be lost.
