As you'd expect the performance is really strong, but I think what is more interesting is the clocks that we got out of the video card today - they were awesome. Looking at the core clock of 1280MHz this is higher than we've seen out of any other HD 7970 which makes us feel that we were right about what these GHz Edition GPUs where capable of doing.
Outside of that, the 7000MHz or 7GHz QDR memory clock is truly amazing. What makes it even more impressive, though, is that it's on 6GB of GDDR5 instead of the standard 3GB that we're used to seeing on the HD 7970.
The Sapphire HD 7970 GHz TOXIC 6GB is truly going to be a video card enthusiasts want for the combination with the out of the box clocks, the clocks you're able to achieve and just the general performance. If you're after a single GPU solution, this is going to be a very enticing one.
What's going to be interesting is what we see other companies do now. Last year we saw MSI release an "Extreme" version of the GTX 580 which doubled the amount of GDDR5 that was present to 5GB. I really wonder if we'll see MSI do something similar with the HD 7970 GHz Edition. We'd say that an updated Lightning video card is even more justified this time as companies have these new cores to play with.
Of course MSI is just one company that we can think of. We've also got companies like HIS and ASUS to name just a couple of others. The big question regarding the model, though, isn't just the price, it's also the quantity we're going to see. This is probably going to be the biggest issue when it comes to the new GHz Edition.
Nonetheless, if you've got the money that the model will carry then this is probably no doubt going to be a video card that gets your attention. If you want to have some fun overclocking as well then the 6GB TOXIC monster will no doubt suit your tastes as you can attain fantastic performance.
