After publishing this article, we got some inquiries on testing the effects of lower memory latencies and Core 2's performance. This is exactly what we've done on this page using the Corsair DDR2-1066 kit that has 2 x 1GB modules with SPD timings of 5-5-5-15. The following table shows the latencies we've used and the results with specific applications

The table above shows that higher latencies dont really effect Core 2 that much- a very different picture than the one painted by AM2 CPUs that rely a lot more on better latencies. This is good for consumers as they can pretty much pick any DDR2 module and expect good performance.
