Best solution for connecting Prism ADA-8XR to Mac Pro?

Best solution for connecting Prism ADA-8XR to Mac Pro?

Currently I have a Prism ADA-8XR with the PT HD card and the AES card. I use the PT HD card 99% of the time, to interface w/Pro Tools HD, and Logic Pro (via coreaudio). The Prism is internally clocked. Like a lot of us I am sick of the Digi Coreaudio driver's 8-channel limit in non-PT apps, so I'm investigating another solution.

On the surface it would seem that I could get a simple PCI-X (like the RME or LYNX) card for my mac pro (mid-2008) with AES I/O, hook it into the prism and simply add more converters to get more i/o.

My question is twofold:

1. Can I get latency as low or lower than when using the digi drivers (I have about 2.1ms in logic now).

2. The PCI cards seem to have internal clocks. Does this mean I have to slave the card up to the Prism's clock, and why is this the case? The PT HD card does not seem to have a clock seperate from the interface? It somehow seems redundant.

I am basically just looking for the simplest, lowest-latency solution to use the Prism with logic via a PCI card.

Thanks in advance.
