Today we take a look at one of the latest graphics cards from Sapphire – the new R9 390X featuring the latest version of their Tri-X cooling system. This top level graphics card ships in an overclocked state and features a custom triple cooler – shipping with 3x 90mm dual ball bearing fans. This card is designed to target the 4K market – priced at £349.99 inc vat in the UK.
It is not always possible for AMD or NVIDIA to release completely ‘fresh' new hardware running on brand new architecture. My colleague Anton has detailed the new range of cards, alongside the previous 200 generation and you can recap on this, over HERE.

| TDP (watts) | 275 | 290 | 275 | 275 | 190 | 190 |
The 300 series launch around 18 months after the 200 series has meant that AMD have been able to enhance the ASIC design by implementing microcode enhancements and the manufacturing processes have improved. We can consider the 390X an ‘improved 290X' – with the added bonus of double the memory – an increase from 4GB to 8GB.
Well, this is not completely true, as Sapphire have been releasing 8GB 290X's for some time now. We were even able to test Sapphire's 8GB VaporX cards in Crossfire, way back in November 2014.
So what do I have in store for you today? For the last week I have been running a series of tests at both 1440p and Ultra HD 4K resolutions – with the latest AMD and NVIDIA drivers – to keep everything on a completely even footing. It is time consuming, but worth it, especially with the release of the new ‘tweaked' hardware. All AMD video cards are tested with the 15.6 Catalyst Beta, and all Nvidia cards the Forceware 353.30 driver.
The R9 390X has been released to specifically target Nvidia's GTX980 so it will be interesting to see how that battle shapes up – as well as being able to take a look at the new card within a broader selection of hardware. Our Fury X review is coming soon, we have had it for some time now.
