As it turns out, it wasn't a typo. AMD are rebranding HD 7000 cards to HD 8000 OEM cards! No changes, false hope subsides :(

Australian? PC Case Gear recently got stock of 'Response' sound dampening material; comes in butyl based sound deadening (http://www.pccasegear.com/index.php?main_page=product_info&products_id=22395) and foam based sound absorbing (http://www.pccasegear.com/index.php?main_page=product_info&products_id=22394)

Linus is right about noctua fans...they undervolt by far and away the best. Otherwise, undervolt some Scythe GTs or Silverstone AP121s

I get the same thing with my 600T's front 200mm fan...try balancing the pressure of the screws.

AMD for pricing, Nvidia for performance and driver support.

2 Asus GTX 670 DirectCU II TOP cards

Recommend an Asus GTX 660TI DirectCU II...that cooler is damn near silent, even under load!

2 x Asus GTX 670 DirectCU II TOP cards (running at 2560x1440)

If you can be bothered waiting, I'm sure there is a dual GPU solution coming in the GTX 700 generation...

MSI 7970 Lightning, for its great cooling, reasonable price and overclockability.

This. Also, as long as you don't load up one of the rails with 3 GTX 680s, I'm sure you'll be just fine!

Generally single card solutions are the best route, especially considering driver support has to cover scaling on the latest titles. Also, you will also have 1GB more useable RAM with the 7970 which will make a difference at higher resolutions, though perhaps not 2560x1600. On the other hand, the 7870s will get noticeably higher frame rates. Your call.

W/m-k stands for 'watts per meter kelvin'. It refers to the heat transfer via conduction; the higher the figure, the better the paste can conduct heat. However, make sure you consider the type of paste (and what you need it for) before you start comparing these heat conductivity numbers. Hope this helps!

Lenovo released details about an upcoming prebuilt gaming PC 'Erazer X700' gaming desktop which claims to support up to 2 GTX 660s in SLI or, more interestingly, 2 HD 8950s in Crossfire! What do we think...typo or accidental reveal? Original article: "A recent press-release by Lenovo announcing the Erazer X700 gaming desktop may not have sounded like much, but it turns out the company is enthused by AMD, particularly AMD CrossFireX, because it is an early design win for AMD's next-generation Radeon HD 8000 series family. The specifications sheet of the Erazer X700 blurts out the graphics subsystem to consist of "up to dual Radeon HD 8950 3GB" as a graphics option next to dual- GeForce GTX 660 SLI. Given that Lenovo chose not to wait until any of the other big tech trade-shows of the year to announce this, it wouldn't be far-fetched to imagine a new AMD Radeon family launch within Q1, 2013. The other more obvious explanations are that Lenovo committed a brutal typo, or it plans to re-brand the Radeon HD 7950, an act that should be made a human-rights violation."

Perhaps not the most reliable option, but I'm sure you'd find something affordable and useful on ebay. Otherwise, most new premium fans (Corsair, Noctua etc) come with at least one...
