Ah latency well that really depends on your PC rig...
On the Pentium 4 desktop my latency is as : 3ms / although run at 5ms
On the I7 rig it is approx 2
All depends on what buffer sample setting you are set to...
Higher buffer setting (ie 1024 = higher latency/longer time) but handle more plugins/sounds/audio streams
Lower buffer ie 128 = lower latency and less plugin/sounds/channels streaming simultaneously
Do a search (I know you been looking) there is loads out there.
On DPC Latency checker I am getting approx 213us (2ms) on 512sample buffer.
Guess it depoends on how many instances of audio your are intending to record at once and your cpu overhead when running plugins and the like.
If youare doin many audio streams it has Firewire 800 or 400 - 800speed provides more bandwidth so more audio streams at once with lower latency settings.
(Im not a pro - so if I am wrong sure others will nip in with an ammendment).
@_@ Of course you have to add the whole routing which can double so a 3ms latency will actually be 6-8 depending on processor latency/midi interface/cbaling/routing and any other hardware/proesses the signal goes through before reaching it destination!?
