Today only. Newegg has the EVGA 02G-P3-1568-KR GeForce GTX 560 Ti (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card for $220 - $30 rebate [Exp 10/31] = $190 with free shipping. Features 384 CUDA cores, 822MHz core clock, mini HDMI, and 2x DVI.
If your focus is on smooth gameplay and not just frame rate averages, Nvidia's Fermi GPU's are no longer a good investment.
