Newegg has the EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card for $190 - $30 rebate [Exp 9/30] = $160 with free shipping. Supports nVidia Physx, Direct X 11, and mini HDMI. Amazon also has it for the same price.
There's such a differance in the GTX660 over this even at this price it's not a deal. Your even better looking at that HIS 7870 @ $200 -AR
"There's a surprise horror show if you click the "legacy GeForce" button, because older, Fermi-based GeForces have a persistent problem with intermittent high-latency frames in certain areas of BF3, including the area we tested."

I have this card and I have no issues with it. I've had it for about a year.
