The Impact of Memory Latency Explored
EconolineCrush writes "Memory module manufacturers have been pushing high-end DIMMs for a while now, complete with fancy heat spreaders and claims of better performance through lower memory latencies. Lowering memory latencies is a good thing, of course, but low-latency modules typically cost twice as much as standard DIMMs. The Tech Report has explored the performance benefits of low-latency memory modules, and the results are enlightening. They could even save you some money."
... Is not memory performance as such, but system performance. If a 5 percent increase in system performance increases the cost of your system by 10 percent, you have to want it pretty badly or be on the edge of required performance or just be in a schoolyard comparison. But if it's reversed, and a 10 percent increase in system performance can be had for a 5 percent increase in system price, then if you can afford the 5 percent (say $100 for a $2000 system), go for it.

I wouldn't buy a $500 card either but, sheesh, at least they're faster than the cheap ones. This low-latency memory is twice the price for a ~3% boost... I think not.
