i think there are some clock speed differences between the 8800gt, 9800gt, gts250. The gt240 is different chip though and slower than all the above. @op I have an 8800gts which would be similar performance. Im trying to figure out how to get a 8gb iso onto 2 dvd's. when i figure that out, ill install black ops and check shadows, not that the iso has anything to do with black ops......just some work i need to do before its play time....Do you have a screenshot of what the "bad shadows" look like so i can compare??
