I'm looking to buy a second 560 to SLI with my EVGA GeForce GTX 560 DS SSC.
Found my card
EVGA GeForce GTX 560 DS SSC (model# - 01G-P3-1466-KR) for 30 bucks more than
EVGA 01G-P3-1561-AR GeForce GTX 560 Ti Free Performance Boost Video Card (model # - 01G-P3-1561-AR).
I had found it for same price last week but it has changed since.
