Asus 3d ready monitor 23" (forgot which model)

I would like to play bf3 and skyrim medium or higher setting in 1080p in 3d stable 60fps. Is this even possible? With one card? Or 460 sli?

Any input would be great.

Thanks

Purchase the Zotek gtx 570 it will work great.

don't ever buy gt400 cards. I had to watercool because of the excessive noise. Still good cards though =)
