i'm currently using integrated graphics nvidia 7050.
im planning to play this holiday season but
i dont know when will the radeon 5670 will come out
The rumor is that the 5670 is gonna come out in January and it is going to be faster than the 9600GT by some degree. So if you want to wait a bit then the 5670 is the best choice, otherwise get the 9600GT and game away.
