Each image is not gigabytes worth of data, it's a few hundred megabytes at best. While the aggregate runs into gigabytes, the processor is not dealing with monolithic gigabyte+ datasets so the potential improvements with 64bit operations are substantially less than the improvements that more capable IO bandwidth can afford. Of course, most of the high-end OS and applications software is being optimized for use on the newer 64bit hardware anyway, because it's currently the fastest hardware around, so whether or not you actually get real 64bit operations is almost a moot point.
