Computer game question. Strange graphics limit

I have a laptop computer. It has an 8 core i7 processor running at 1.73GHz. I have 4GB ram and am running windows 7x64. This brings me to my question. I have black ops on my computer. I can up the graphics to a certain level (I forgot what the exact stats are) and the game runs fine. After that, the frame rate has problems. As long as I keep it below that level, I've never seen a significant drop in frame rate. If I exceed that, I always see a significant drop in frame rate. More puzzling, I can run as many programs as I want without any problems. I've been running a virus scan, outlook, several instances of two different web-browsers, several word docs, had an excel doc open, and a bunch of other programs and the game ran just as well as when I had nothing else open. The only exception was that it took a few seconds longer for a new map to load than when I wasn't using any other programs. What's going on? Why is there that limit? Why is it that as long as I do not exceed that limit, I can run as many programs as I want and the game can be run just as well as when I have nothing else running? I understand that my computer has limited resources, but in my understanding, the more other programs I have running, the worse the game should run. Why is there no change in performance no matter how many programs I run and why can't I increase the graphics without having a large drop in frame rate?
PS: Every time I start the game it says that "Your computer appears to have changed sense the last time you ran Call of Duty." It then asks if I want the game to configure itself to my new hardware. Why does it say this? I haven't changed any settings/hardware recently yet every time I run the game it gives me this message. My best guess is I've heard that the i7 will automaticly overclock if it needs to. Could it be that the game is realizing that the clock speed has changed and it is thinking that I had updated my cpu? Or is it likely something else that it is seeing? Thanks for the help.
 
I'm guessing you got Core i7-740QM or a Core i7-820QM, both 4 cores / 8 threads processors clocked at 1.73Ghz. Not that it really matters since your problem is obviously caused by you GPU, it simply cant handle the higher settings.

The reason running other programs in the background does not cause a massive drop in performance is because of your processor 8 threads, if you have a good SSD it would make it even harder to overload you pc with tasks.

As for the reason the game says your pc has changed, i have no clue. Its unlikely that the CPU speed is the reason since most processors have had CPU throttling technologies starting from the late 90's.
 
The game is probably just not writing the config every time you start, so when you do start, it looks, finds no previous config and goes "oops, you need to do this".
 
The Call of Duty games always say your config has changed even when it hasn't. It's been that way since at least COD4. Just say no, otherwise it will reset your settings away from what you prefer. It might be the CPU speed changing to save power that triggers it, but COD is definitely oversensitive in that area.

Fëanor is right that it must be your graphics card that isn't up to the task of the higher graphics settings.
 
Ok, thanks everyone
