Or an engineering mistake, low latency and PCI performance is not exactly 
top priority in todays computer world.

I have an i5 (4 core no ht) and a D66, which is the same ice1712 to the 
PCI bus as the OP. No problems. I have an azus MB which I chose for 
maximum number of PCI slots (3) so I had as much choice of slot as I could 
get. I chose minimum on board bells and whistles because those are just 
more to get in the way of my audio. Intel video (on chip) and even ps2 
mouse and keyboard. (I have an old mechanical KB that has a switch for "at 
or xt" to show how old it is). While I don't use a USB Audio Interface, I 
don't like USB mice if I can avoid them... I have found USB interrupts 
troublesome in the past. The only USB device I have is a scanner which is 
turned off when not used, plus the odd USB mem stick and a second keyboard 
I use with midikb as a controller sometimes for testing. Audio is not plug 
and play really on a PC (win or linux) if you want low latency it needs 
exrta work. Linux at least gives one the tools to do that.
