Topic: New System and HDSPe AES

I am assembling a new system based on ASUS P6T6 WS Revolution, HDSPe AES and Windows Vista, probably 64 bits. I have been using so far an usb interface and moving to HDSPe AES (PCI Express) interface, I understand that I have to install it in a way that HDSPe AES will not share any resources with others devices on board on the hub like, video card, raid card and etc
Any suggestion how to do it? Does It really give advantages?
