What's the way to go here? Since my 'very special' offer at Amamzon.de has been withdrawn by the dealer, I am having some time to find an ideal 7970 for me. Which are the best brands and designs to look for, especially regarding temps, noise, OC potential and support?

Before considering some reference design, I did set my eyes to three toys:

MSI Lightning http://www.newegg.com/Product/Produc...82E16814127670

XFX DD http://www.newegg.com/Product/Produc...82E16814150632

VisionTrek (I think it's VTX3D over here): http://www.newegg.com/Product/Produc...82E16814129265


As it will do a lot of POEM, I may neglect noise, but I don't want to leave the house every time I am running Dirt.
