hi, which pci slot of the msi neo2 can be recommended for audio? which has its own irq?

i am going to install my delta66 into the new asusp4b533. Does it make a difference which pci slot i use? This will be the only pci slot i'll be using.

I don't know much about IRQ's, and i want the absolute most performance i can get.

I'm thinking about postponing my upcomging P4 (GNUS) machine to wait for the new 133/533 bus, and give it some time to test out and let prices fall to boot...
