does the intel 5000x MCH support PCI Express peer-to-peer

Hello, all, I'm not sure if this is the right forum, but I figured HPCC guys might know the answer : we're trying to build an application with two PCI Express cards in a Dell 2950, which uses the 5000X MCH. The question is if the MCH will allow peer-to-peer writes.

I looked thru the MCH datasheet, but it doesn't come out and say it, though there are some hints. Can someone confirm if peer-to-peer is "officially" supported ? Does it provide normal, close-to-hardware latencies, or is it a wimpy path that's not meant for real heavy duty use ? Does using peer-to-peer detract from the hostor DRAM bandwidth (say if no-snoop is set in the write requests) ?

Please let me know,orif there is some other forum or method to get this info.

Disappointing to see lots of views, but no replies to this topic. Please let me know if I should ask on some other forum, or if there is somebody at Intel who can help.
