emulated ports and MOTU/RME

I’ve just upgraded to a new 64bit win7 system and this means I have to ditch the midex. So I’ve bought a MOTU express 128 which does have win7 64bit drivers.

What’s the current opinion regarding timing on the MOTU stuff - do I need to use emulated ports - system timestamp ? do I need to disable the high precision event timer (HPET) on the Asus p8p67 motherboard.

Just to make life more complex I’ve also bought the RME raydat which has a couple of midi ports that I’d like to use - as they claim very low latency/jitter. What setting would suit these ?

thanks
