I tested my GT220 and no line, so it looks it's a problem with the GTX460's like Radiance said.
Sublime - you should check and see if you have another black line on the right most side of your image like pixelrush and I do. I'm guessing you have one there too, although you can't see it if the image is larger then the view port will display. At the standard 1024 X 512 resolution I had to enlarge the view port to see mine. The line on my system is different then yours and pixelrush's, mine is white with colored noise. Much easier to see I think.

You can fix this ( users ) by poking around the resolution a bit. You might experience some oddity now and then but Im using 2 460s and my frames are flying through the engine like a mad with no lines.

Same issues here with 2-Palit 460 GTX. But, if I change the resolution, the line goes away. But only if I go up in resolution.
Another issue I'm having. System totally locks if I make any material 95%+ transparent. Same thing when adding a transparency map to say a leaf texture.

it looks like you have to play with it, but it's only the x resolution that is affected. All base 2 numbers I tried had the line in it (128, 512, 1024, 2048). It's probably something to do with how the image boundaries work in the cards memory and processors. It will be nice to be able to use CUDA 3.2.

yeah, the resolution tweak apparently works, look forward for the proper fix with the CUDA driver etc. What a one big lovely family,..
