Choosing between AIW cards, purple vs. domino cable?

[aramkolt]

I am trying to decide between these for standard analog to digital VHS conversions:

9000 64MB with DVI port - Says AGP 2x/4x - will this cause problems with an AGP 8x Motherboard slot?
9800 128MB with DVI port - AGP 8x

The 9800 is much more expensive and has more ram, but I am not sure if it actually produces better results?

The motherboard I plan to use it with is an Asrock P4V88+ which says it has an AGP 8x slot. Not sure if the 9000's 2x/4x spec will decrease performance for our use case, or if it has issues working in an AGP 8x motherboard slot?

If there's a better variant to look for that doesn't require impossible to find breakout cables that I should be looking for instead?

Is the purple "Domino" input cable the same as the non-domino/solid purples one in terms of pinout/interchangeability?

Thank you in advance!

Get 9000. For video capture, no difference in 9000 and 9800.

DVI output models lack need for special cables, like 9600.

Yes, domino = purple.
Tip: domino usually nasty, harder to clean, white yellows. So get purple.
