PowerColor HD6990 LCS Review
Published: 17th July 2011 | Source: PowerColor | Price: £619 |
As part of our Shadow H20 there are a few slightly different specifications to our normal test setup. However we are sure that the system is close enough to our normal one to maintain the validity of results comparison. The only change to be wary of between the PowerColor HD6990 LCS and the other results in our graphs is that they were done at 1920x1200 and this is 1920x1080, so they'll be a slight improvement as there is 230000 less pixels to render.

Without the heat problem restricting our overclocking efforts the PowerColor was capable of some serious extra oomph. The GPU falling just shy of 1GHz and the GDDR5 having an extra 150 MHz.
Proving how efficient a water-cooling setup is, especially for graphics cards, we saw a maximum temperature of only 50°C. This is an incredible improvement over the 80°C-ish that we get from the stock air-cooled card.
Let's get down to some benchmarks.
