9600 gt or 8800 gts

I am in jordan and there are very few high performance graphics cards avialable, I want to upgrade my 9500 GT, and I found the 9600 GT and the 8800 GTS 512, the 8800 GTS 512 is about double the price of 9600 GT, I know that both are somewhat old cards but that what I was able to find in the retail stores, I play games occasionally, my monitor resolution is 1440*900.
The question is: Is it worth to go for the 8800 GTS 512 for double the price?

The rest of my spec:
intel E7400
2 GB DDR2 800
250 GB hard disk western digital
300W power supply (I will definitely change it if I get one of the above cards)

Thank you

If you like playing Crysis or Fallout 3 on a good resolution go with 8800 GTS, 96 cores vs 9600gt with 64 cores.

What is the price for the both graphics card?

like zafer said it depends on the games if you are really into crysis i would get the 88 but if not u are only okaying at 1440x900 so the 9600gt should suffice to play all the other games fine
