The Radeon R7 family name will adorn cards that range from mainstream to midrange (that is, under $199), and the Radeon R9 will signify the pricier enthusiast line, starting with the $199 Radeon R9 270X, and eventually ramping up to a promised Radeon R9 290X. The Radeon R9 280X we’re looking at here falls between those two, and stock versions of it are expected to sell for $299 in a 3GB memory configuration. AMD expects Radeon R9 280X-based cards to be on sale from various third-party card partners by Oct. 11, 2013.

Direct legislation — a law limiting the amounts that anyone, challenger or incumbent, could spend on an election — would obviously be beneficial.

But if he doesn’t stop forcing balls and taking risks out of desperation, the ball-hungry Bears are going to add to his misery. Stats don’t lie. The Giants lead the league with 13 INTs and seven lost fumbles. The Bears are second in total takeaways — the traditional starting point of their defense — with 14. Like last week against the Eagles, Manning can attack a safety corps that has broken down against deep balls over the top.

This was actually the first site to receive official U.S. National Monument status (1906). It’s on every climber’s bucket list, but only a tiny percentage of people who make the pilgrimage dare to scale the summit of this 5,114-foot rock monolith. Sacred to the Lakota Sioux, the site figures into several native peoples’ creation lore. Accordingly, there are many ancient names for it, including Bear’s Lodge and Bear’s Lair.

Third, failure to address peak oil and its implications. Fourth, over-reliance on military keynesianism, often accompanied by outright aggression and subversion of other nations: All at immense cost. Fifth, a willful effort to dumb-down the general population through a complicit media and a carefully crafted policy of economic restrictions on education. Sixth, a failure to provide for the aging of the population. Seventh, a failure to address the terrible costs of privatized health care, and much else that should be in the public sector from jails to street construction. Eighth, a bizarre and ideological form of financial and business deregulation and turning a blind eye to the political corruption fostered thereby.
