In a move by nVIDIA, both the GeForce GTX 280 & 260 have received large price drops, in response to the competition from AMD/ATi's HD 4870/4860 series. More info. in the Fudzilla article below and the Newegg.com price links for both the GTX 280/260.

They're pretty large price drops, with the GTX 280 dropping over $150 USD and the GTX 260 dropping a $100 from the original MSRP price. I'll still will wait another month until the HD 4870 X2 comes out, which will likely incur more price drops. Yay for competition!
