you machine would still be good for surfing, MS office, etc.... but for gaming... yea sorry... your right... I would suggest getting a new system. BUT if you can't... then I would first reformat. give it a fresh load. Then see what happens... from ther if you still have issues, upgrade the GPU... you can find decent 6800XT's for about 160-180 USD (Sorry, no CD)... Second, then I would upgrade the ram... Go with some decnt 2X1GB ram... But first try that reformat... that should hold you until you can save some money and get a new build.
