For a DB load the cache snoop handling should have no really noticable impact. Those loads tend to pin tasks to particular CPUs anyway and tend to be IO bound - and there you will gain the most from the huge improvement on PCI throughput availibity. Depending on how you stuff your system with IO subsystems this could have an overallimpact even on the order of hunderd of percents. And then of course remember that you can staff more RAM in to the system.
