We reviewed the reference AMD HD7970 flagship card in December last year and we were suitably impressed. A few weeks later XFX sent us their XFX R7970 Double Dissipation graphics card which featured a custom cooling solution. Today we look at the latest version of the card from partner VTX3D – The ‘HD7970 X Edition' is the first HD7970 we have reviewed which features not only a modified cooler, but overclocked core clock and memory speeds. Is this good enough to get the Kitguru seal of approval?
It would be fair to say that VTX3D are a little known player in the graphics sector, although they are trying hard to raise their profile with the enthusiast gamer. They are a division of Tul Corporation, who also manage the more widely known PowerColor series of hardware.
VTX3D are a subsection of Tul Corporation who focus on achieving the lowest possible price points. For instance, their last generation dual GPU HD6990 was priced at £515 inc vat on Amazon, when others were £599 inc vat.
VTX3D know they have a lot to prove in the enthusiast sector, so are they any good when it comes to batting head to head against the big boys, such as Sapphire and XFX ?
The X Edition card we are reviewing today certainly ticks all the right boxes on paper. It ships with a custom cooler, dual fans and significant out of the box clock speeds.

Above, we can see how the VTX3D Radeon HD7970 X Edition slots into the marketplace (clock speeds marked in bold). The core clock speed is increased from 925mhz to a whopping 1,050mhz out of the box, and the 3GB of GDDR5 memory receives a tweak from 1,375 mhz (5.5 Gbps) to 1,425 mhz (5.7Gbps).
Wow thats a great product, surprised how well it handles.
What is their warranty support like though? Powercolor had a terrible coverage plan in the UK.
I dont think it looks that bad. anyway who looks at a video card anyway, once its installed, its out of sight, right?
Wow im buying this, ive waited for a while now for a good 7970 with quality cooler. none in stock yet, another week before its available 🙁 damn you kitguru for getting my hopes up.
Well some difference there is… as i checked warranty times from one shop for some 7970 cards. MSI, ASUS, Gigabyte offering 3 years on the ones i checked. XFX 2 years and this one has 1 year. I bought this one anyway.
