How noticeable is the difference between a 128bit and 256bit memory interface?

On either the ATI or Nvidia cards.

Totally depends on what resolution you are playing in. Mid to low resolutions no noticeable difference really. High resolutions big time difference at least this is what I have noticed.
 
Also depends on the amount of memory... for instance, way back when a friend of mine got a 9600(non-pro) with 256mb of memory. Yet, the 9600 series only had a 64bit bus, and the processing power of the the 9600 was weak to begin with... what a waste.
 
It depends on several factors like mentioned above. If you can post the cards you're considering and what resolution you want to play games at that would help decide.

One example is a 6800nu or 6800GT (256-bit memory each) vs a 7600GT (128-bit memory). The 7600GT would win in almost every benchmark, regardless of the resolution.

he had a crap 9600 my 9600np had 128bit bus with 256mb of memory
 
I haven't really started doing video card research yet, but what I do want:

ATI
256mb or more

I usually never play at anything higher than 1280x1024, but if my card can push out the graphics then I might raise it up, but I'm ok with 1280x1024.

Here is a quick search I made on newegg

I have the option of a fanless or with a fan for cooling, what performs better?
 
Dont forget that a 256 bit bus will help tremendously with higher AA and AF and its when you go to higher resolutions you can really tell the difference.

Good point. To clarify you have to compare same generation of cards too!
