SDRAM--->DDR--->DDR2--->DDR3=more bandwidth, more latency, lower voltage and lower heat. After a decade and dozens if not hundreds of hardware reviews that show minimal to no real world performance improvements (synthetic? Uh huh!) DDR3 is another solution to a problem that doesn't exist. Only when speeds get well above DDR3 2500 will there be significant and noticeable speed improvement.
DDR3-1600 is a very significant improvement over DDR2-800... the issue is that Core 2's are hooked up to memory controllers the other side of the an FSB, the IMC in the i7 delivers... heroic bandwidth from DDR3
The problem does exist, but the memory always always ALWAYS comes before its needed, in this case it came in the middle of the Core 2 generation, when it wasn't needed or useful until i7
One exception to this is DDR memory coming with the Athlon (huge performance kick)
