Playing Call of Duty 2 with the 8800GT is jerky and playing it with the same settings with the 7300 is smooth... why? I have the 8800GT in the FIRST slot (16x) and the 7300 in the 4th slot (8x). It should not be doing this. It's not like low framerate jerky, it's like smooth-skip-smooth-skip-smooth-skip-smooth-skip and so on... It's like a pattern. It's worse when there's fighting going on but, the 7300 is sooo much smoother. I don't understand why it's doing this! I am pretty sure I installed the card correctly. Mac OS X works just fine with it, no skips or anything there.
