Ideally you want to really target the $125-175 range for mainstream cards. Those cards will be considerably more powerful than the sub-$100 range.

Evga GTS 250
Evga GTX 260, Core 216
$140 - DX11 compliant (if I recall it's power is a touch lower than the less expensive GTS 250)
$175 - DX11 compliant (bounces around the performance of the GTX 260, typically a hair lower)
