Newegg has the EVGA SuperClocked 01G-P3-1461-KR GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card for $185 - $15 rebate [Exp 8/31] + $0 shipping = $170 shipped. Features 850MHz core clock, 2560 x 1600 max resolution, and 1x mini-HDMI and 2x DVI outputs.
A SSC FTW at 850Mhz, though I can't find any differance from this a the 01G-P3-1463-KR other than the curved shroud on the -63 appear to kill some exhaust. Hard to find good reviws on non-ti's like this.

Still a little pricy compared to a 6870
