by Matthew-Murray (Sep, 2011)No, the games won’t look the absolute best they can, but they’ll still look fine — and play well.
by Khalid-Moammer (Sep, 2014)It’s widely speculated that this is the cooler for the R9 390X.
Features Key features of the Radeon R9 285X
memory bandwidth Rate at which data can be read from or stored in onboard memory
pixel rate Number of pixels a graphics card can render to the screen every second
texture rate Speed at which a graphics card can perform texture mapping
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

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.
