Your RAM and CPU shouldn't be causing slow running - both are quite reasonable on a mid-range PC. However, for gaming you need a powerful 3D video-card and you haven't mentioned it's spec. Also, a fragmented disk can slow down your system, as also can a boot disk which is getting full. Buying a SATA disk is pointless unless your mobo has a SATA controller - only new mobos have them.
