For this review today we aren't comparing against the array of products we tested in 2012. Instead we are comparing directly against an ASUS GTX690 and two Sapphire HD7970 6GB Toxic Edition cards running in Crossfire. All cards are using the latest Beta drivers at time of release from both Nvidia and AMD, placed inside an overclocked Core i7 3960X Extreme Edition system with 16GB of 2,400mhz memory.
The Sapphire HD7970 6GB Toxic Edition was one of the fastest cards we tested in 2012, so we thought that adding two of them into a Crossfire configuration would make for an interesting comparison.
The Sapphire HD7970 6GB Toxic Edition is hard to get hold of now in the United Kingdom but the retail price is around £550 for each card, bringing the total cost to around £1,100. This is the most expensive solution on test today and has a combined GDDR5 memory count of 12GB. We run both cards with ‘Lethal Boost' enabled, setting the clock speeds to 1,200mhz core and 1,600mhz memory.

All the latest BIOS updates and drivers are used during testing. We perform generally under real world conditions, meaning KitGuru tests games across five closely matched runs and then average out the results to get an accurate median figure. If we use scripted benchmarks, they are mentioned on the relevant page.

dear lord, my epenis is so small right now 🙁
Seems like a great price point, even though it costs as much as my system im working on right now!
Bit of a bargain for the high end gamers with loads of disposable budget.
both this and the GTX690 are quite power efficient, considering!
Would have been nice to see two HD7870 Tahiti LE’s in CF, just to give a viewpoint of what could be achieved with around £400.
Good review otherwise, dream system material
Seems I got one of the five left 🙂 just in time ! thanks for review ! awesom!
what power supply will you be using Tom?
just ordered a 1000W Seasonic, as I needed to move up from my older 750W corsair.
Costly day, I hate this site sometimes 🙁
Sadly the framerates DON’T tell the whole story as Hardocp and Tech report have shown, crossfire might show higher framerates but real world game play is not as smooth as SLI.
Real world gameplay was perfectly smooth on the HD7990 with the latest AMD beta drivers – unless there is a Crossfire glitch with a specific game I didn’t test (which is possible as that can happen). I was playing games on it for a few days.
Wow, this thing is ridiculous, I need a new card lol
