Core2 Duo Preview : Core 2 Memory Latencies
 

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.

so even with the cheapest memory sticks out there you'll get extreme performance, almost too good to be true:)
