Those are the theoretical maximum values for bandwidth. Also the bandwidth figures are for DDR2 667. With DDR2 1066, the bandwidth figures will be way closer. The chip will never reach those in practice as its limited by FSB. If you look at the AT article you quoted the difference in buffered bandwidth between DDR2 at 800 5-5-5 and DDR3 at 1333 9-9-9 is insignificant (~200-300MB/s) with the latter having significantly more latency and hence negating the bandwidth advantage. In actual applications, the performance difference is insignificant... under 1%.
Shuvd you can buy an E8xx series CPU without any issues and run it with DDR2.
