My own personal thoughts are that the Radeon R9 280X will soon see an official price toned down to $279 US while the Radeon R9 285X makes its way in the $299 US league.

In The News From around the web

The increase in games would come from the crappy Crossfire support in some games, but with games with great multi-GPU support, the HD 7970s in CF would still be a great rig.
My question should I upgrade my gpu to the r9 380 x 8 gig of RAM or is there a better option also will my cpu hinder performance.
It’s widely speculated that this is the cooler for the R9 390X.
In case you’ve missed it Videocardz.com put out a story yesterday claiming that AMD may have cancelled the R9 285X.
As for the power consumption, the FirePro W7100 has a wattage of 150W however being a Firepro variant, AMD had to tone down the clock speeds.
Tonga which is a performance oriented offering for the consumer market doesn’t has to face those restrictions hence AMD has the Tonga Pro chip consuming a total wattage of 190W which is slightly lower than the Tahiti and a good 40W above what AMD advertises for the W7100 but it has higher clock speeds and support for better PCB designs from custom AIC board makers.
