There is something wrong with the power circuitry in the card and how it affects the analog signals originating in the card. Besides pure digital signal, the only other solution has been to remove the additional 4 pin power connector. At this point there are only a few things we can do:
1) RMA or hold off buying 59xx and wait for NVidia to give us official information... something that is looking less likely every day, probably because they realize the enormity of their blunder.
2) Buy the 5900 SE cards coming out this fall, with freshly made GPUs from IBM and hopefully better board circuitry.
3) If 5900 SE is still flickery, wait for NV40 in the spring to fix this. (I'm not that patient.)
4) Switch to ATI and deal with their continued buggy drivers but SOLID picture.
Personally, I am going for option 2, followed by option 4.
It would make no sense to wait and buy the SE line of cards. The 5200 SE, 5600 SE and 5900 SE are being introduced as a value line of cards that will be clocked lower. The Ultra will still be the top card.
What we need to do is wait for a fix whether it be software or an RMA. Or like you said you could move to ATI and deal with a load of other problems.
