Price in Amazon pretty steep so bought this from an independent reseller.
DX11 is absolutely gorgeous, I tested it using Black Ops and blood gore never looked so good.
Full-load the fan noise sounds like a turbine engine, totally noisy, thinking of either bypassing the fans connection to the card and splice a fan controller or surround the case tower with honeycomb cardboard to minimize noise.
(edit: turns out, the noise came from the stock CPU fan, replaced it with a sunbeam-labeled cooler, noise is now gone)
Plan on buying another one to really complete my first crossfire setup.
(edit: did it, played crysis 2 on HD, no slowdown whatsoever)
My rig:
AMD Phenom X6 1055
MSI 890FX (5 PCI-e x16 slots, shame can't use all of it)
8Gb DDR3 RAM
1Tb WD Blue (yeah i know, should have bought the black but budget woes prevented me)
