nvidia GTX 590 single and SLI Reviev = total FAIL? This card can BURST INTO FLAMES!

So yesterday the GTX 590 had it's premiere and the performance is not very impressive compared to Radeon 6990. In most cases the Radeon 6990 is much faster especially in very hi resolutions like 2560x1600.
Second it takes more power than 6990 both idle and Stress.
but it is quiet and the temps are nice.
I was surprised that even in Quad SLI the the 590 is slower than Quad Crossfire 6990
And third yes the clocks are low compared to GTX 580 so the leak is confirmed
ALSO ANOTHER BIG THING!
This card has some technical difficulties that can cause a permanent damage!
PC websites are reporting that when it is overclocked it can be damaged or sometimes it can be damaged even when the card is ruining on stock speed!
I have to tell you that I am surprised! The nVidia was almost always faster than radeon and now something is wrong
