I own the 80-200/2.8D. I was considering selling it to purchase the AF-S as well because of the focusing. I noticed the difference in my 50/1.8D and 35/1.8 AF-S in terms of noise and focusing speed. The difference is incredible. It was a similar difference between the Sigma 18-50/2.8 (non-hsm) and Nikon 18-70mm/3.5-5.6 AF-S. The focusing on the AF-S nikon was incredibly quiet and smooth. Sometimes, I had to turn the camera, focus on something that I knew was not on the same plane as the subject, turn the camera back, and focus again so I could see it focus. It seriously was that quiet.
The 80-200/2.8D may not have a focusing motor, but the focusing 'torque' I guess you'd call it is miserable sometimes. Also, the focus is very distinguishable on the rare occasion that it hunts. So, yes. I can see where you are coming from with saying it is louder. Once you've heard something with AF-S..or..not heard it I guess, you will learn to dislike every lens without it just that much more.
That being said, the lens produces amazing photos. Id lay my money to say they are probably exactly the same quality as the AF-S verison, and almost as sharp if not on-par with the legendary 70-200/2.8. I absolutely adore mine and upgrading to the AF-S version just wasnt monetarily feesible for me. When I do upgrade, it will be to the 70-200/2.8. If you have to get the VRI model, its still better and about the same price used as the 80-200/2.8 AF-S new. I cannot tell you what to do, but this is what I would do.
You should rent one for a day, or borrow one. Or even just go to a local camera shop that carries them and try it out first before you spend the money. It may not be worth the extra $300+ in the end.
