PowerColor HD6990 LCS Review
Introduction and Technical Specifications
Published: 17th July 2011 | Source: PowerColor | Price: £619 |

Introduction
When we first reviewed the HD6990 we found it to be a phenomenally impressive card. A total powerhouse. However the main issue was, as it is with most of the current range of Radeon cards, heat and noise.
The perfect solution to any heat problem is to go from air-cooling to water-cooling. Modern CPU coolers are of such high-quality that water-cooling isn't such a desperately important thing for the heart of our machines, but graphics technology has continued apace and almost outstripped the capabilities of standard air-cooling to keep the cards cool. So water-cooling is ideal for our power-hungry, eye-candy providing behemoths.
Enter PowerColor with their take upon the HD6990 with a factory fitted EK Waterblock. A perfect opportunity to get a system built we think.
Technical Specifications
Aside from the addition of the EK Waterblock, the PowerColor HD6990 is a standard card beneath that Delrin exterior.

(Results in the oc3d reviews are still troubling me, especially when you look at same cards with better settings, where, to be fair, they really can't be slower.)
Ultra damn fast fps for sure. No quality and physx for me tho.
I actually thought it would be more expensive.Quote
Personally I think any card that comes with a waterblock by default should have some sort of voltage tweaking so you can better exploit the extra cooling potential.
Also on the side note:
Call of Duty - Black Ops
If you're a fan of the Infinity Ward shooter then you have nothing to worry about here, or to be honest with any card. WTF
