What!!!!, you actually ordered for the Fx5700U, inspite of having the 9600pro, why??. You should have gone for a higher end card instead of wasting your money for a card of the same mid-range level. Plus the Nvidia FX series sucks at dx9.0 games ( now you will have to play HL-2 using the dx8.1 path, instead of the dx 9.0 eye candy effects which were possible on your 9600pro). You should have gone in for the 6600GT AGP, or better waited, saved up some money and gone in for an x800xl (AGP - which is expected to release in two months time - I think).
You could have sold your 9600pro for say 6k or abouts (assuming it was 6 months old) and put in some more for the 6600GT, OR gone in for the more superior (to the 9600p and the 5700U) 9800pro/xt. Can't your order be cancelled or something?.
Anyways, I hope you do well in your exams.
