Not to be rude but you really need to upgrade everything... Your CPU and your gpu are very dated. I would suggest saving up and just buying a new computer... You should go i7 and Nvidia in terms of cpu and gpu.... Currently I have an i7 3770k and a Asus Nvidia GTX 570 and I got 9k on my benchmark with everything maxed. The 570 is fairly cheap now... I believe around 150....
