OPENGL 4.5 LINUX SERIES
The AMD 300 series are mostly re-branded SKU's from the 200 series with minor clock tweaks and some with more VRAM than their older cousin, there is nothing really new happening there. Other than the FuryX which does cost more than the 970.

Maybe I'm wrong, though, and real world performance will prove the 970. Quoting: CrashWith a similar core clock, 384 vs 224 GB/s memory bandwidth, a 512-bit vs 256-bit memory interface, double the GDDR5, and about 50% more cores, I'm having a hard time justifying the 970 which is similarly priced.
OPENGL 4.5 LINUX DRIVERS
Here's to hoping we don't need to buy new hardware and AMD will finally get their drivers fixed ( I read a lot of negative experience with ATI on linux, I ditched ATI a long time ago so I don't have any first hand experience)
OPENGL 4.5 LINUX PC
Judging by the Steam Hardware Survey those specs also encompass quite a huge amount of the PC gaming community. basically any GPU purchased after late 2009/early 2010. OpenGL 4.3 support extended back to the Nvidia GeForce 400 series and the ATI Radeon HD 5000 series-a.k.a. On the PC side, that equates to OpenGL 4.3, released in August of 2012.

That basically means any GPU that can do compute shaders." "Any hardware capable of supporting OpenGL ES 3.1 will be capable of supporting Vulkan. We have a very specific goal," says Trevett. Just like DirectX 12, Khronos is hoping to extend compatibility back a few hardware generations, which means you'll potentially notice a performance increase even on your old hardware once the API is officially released and introduced in new games. QuoteAnd good news for basically everyone: You probably won't need new hardware to take advantage of Vulkan. Although a few people on our forum have noticed an improvement in performance with the 15.5 Catalyst driver. It's great to see them promising higher OpenGL support, and I hope they work on their stability some more. It will be interesting to see when Nvidia & Intel will officially support Vulkan. That's speculation on my part though, but I still think they will use Vulkan as a selling point rather than make it backwards compatible on older cards. If they are advertising it as a feature on their brand new line, it's probably they won't add it into previous cards, which will be a shame for a lot of people. It's promising that they are mentioning Vulkan already! Although until we see Vulkan officially released and usable in some games and benchmarks it's not all that useful. QuoteDirectX® 12, Vulkan™ & OpenGL® 4.5 APIsīattle-ready with optimized performance for next-gen APIs (DirectX® 12, Vulkan™, OpenGL® 4.5, Mantle) and is designed from the ground up to give you everything you need to enjoy the latest games today and tomorrow.6,7,8 AMD has launched their new AMD Radeon™ R9 Series, and with it comes a promise of OpenGL 4.5 and future Vulkan support.
