Mac Pro and the memory latency issue

In the article on mac pro posted here on AT som time ago it was concluded that "FB DIMMS kill latency"

"And here we see the real killer with FB-DIMMs; although the Mac Pro boasts lower latency memory accesses than the PowerMac G5, it actually takes longer to access main memory than the Core Duo processor in the MacBook Pro. This is much worse than it sounds once you take into account the fact that the MacBook Pro features a 667MHz FSB compared to the 1333MHz FSB (per chip) used in the Mac Pro."

Does any one know how this will affect me in practice? What kind of tasks are effected and how much.
 
Sorry for the late response, but I've got 6GB and not a single problem... performance in UB applications is blazingly fast!
 
latency is slow but that is actually intel's fault. (they invented FB-DIMM and their only compatible chipset for dual xeons requires FB-DIMM.) read the article. if they can get regular DDR2 at some point, it will be even faster. you can rest assured though that it will last.

Mac's don't lose value as much plus anandtech had it running dual kentsfield for a total of 8 cores without a problem.
