Radeon R9 285X 

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.

Today during AMD's live stream event celebrating 30 years of graphics and gaming, the company spent a bit of time announcing and teasing a new graphics card, the Radeon R9 285X and R9 285.

Clock speeds on Tonga look like they are just slightly lower as well.
