128 bit vs 256 bit video cards

What is the differnece? does the 256 bit cards have better preformance? does any game require a 256 bit card? because I'm thinking of getting an ATI 4770 (128 bit) over a 9800gt (256bit).

the bits there is the fill rate on the gpu in short the higher the fill rate the better stuff like motion blurr and post process effects look. they can be a big deal for someone say trying to achieve benchmark scores in say gta4 or crysis but are immaterial to us simple folk wanting to max the games we love with high fps. though speaking frankly a 9800gt lacks the horsepower a 4770 does due to its energy efficient nature and use of the same template an an hd 4850 (on par with a 9800gtx+ overclocked by a significant amount.
