On-board sound = instant disable in the bios for me. The only thing good about onboard sound is that a gameport is usually built onto the MB then.
As for ISA slots, why do you think the Abit is slower?
The a7v133 can use jumpers or bios to set multiplier.
I have nothing against Abit Kt7 or kt7a, they are both great boards as well. The Asus is a bit faster and more stable though. In the US the price difference is not that large. Maybe in the UK it is different?
All newer MBs share interupts between PCI slots. The configuration for the a7v is: Pci 1: Shares with AGP Pro slot
Pci 2: Shares with Promise onboard ata100/raid controller
Pci 3: Shares with nothing
Pci 4: Shared with Pci 5
Pci 5: Shares with pci 4 and/or amr slot (useless btw)
My setup is as follows:
Agp slot: Video card
Pci 1: free (I have a fan in this slot)
Pci 2: network card (I disabled the promise controller, I don't use it.)
Pci 3: SB Live! value
Pci 4: modem
Pci 5: free (USB expansion card in this bay)
