I read the article and I think there's a bit of scaremongering going on.

Did you see the eye diagrams? They are all perfect, though the article
says some of them are nearly out of specification.

The specification will ensure that you still get a workable picture over 
an X metre long cable; if you keep it short, it won't matter if you 
card IS out of spec.

The NVIDIA cards with the off-board SIL164 transmitter chip seemed to do
better than the ones using the built-in transmitter in the GeforceFX
(especially obvious on the card with one of each, the MSI NX6800
Ultra), so if you are concerned, look for a card with that chip.
I expect it'll only be on the more expensive cards though.
