Gigabyte Ready with GTX 470 SuperOverclock
Gigabyte displayed its high-end non-reference GeForce GTX 470 based graphics card, the GTX 470 SuperOverclock (GV-N470SO-13I). The card is built using Gigabyte's Ultra Durable VGA Plus (UDV+) technology, and makes use of a 12+2 phase VRM, because of which the PCB is about as long as a GTX 480. The GPU and memory chips used are said to be hand-picked (by binning), to have the highest overclocking potential. The GPU cooler used is no less complex, making use of a large aluminum fin array that's cooled by three fans that's are slightly inclined to reduce turbulence. There is no word on the clock-speeds, though being an SOC model it will likely be on the higher side.

Galaxy Designs Non-reference GTX 480 with Vapor-Chamber Cooling
Galaxy displayed a new GeForce GTX 480 graphics card that uses non-reference design PCB and cooling. The unique selling point here is a cooler that Galaxy claims to be superior than the reference, making use of the Vapor-chamber technology for quickly transferring heat off the GPU to the heatsink. It also features a very Gundam-styled cooler shroud the company has been toying with on several of its recent designs. The GeForce GTX 480 packs 480 CUDA cores, and 1536 MB of memory across a 384-bit GDDR5 interface. Clock speeds are not known at this point.

New HIS HD 5570 Silent Pictured
HIS designed a new silent Radeon HD 5570 graphics card. Having a silent design, the GPU is cooled by a large heatsink that takes up two expansion slots, and uses ridged aluminum fins to increase surface area. As with every other HD 5570, it is based on the 40 nm Redwood GPU, having 320 stream processors, DirectX 11 compliance, and 512-1024 MB of GDDR3 memory across a 128-bit wide memory interface. Display connectivity includes one each of DVI-D, HDMI and DisplayPort.

ASUS Displays ROG Immensity Concept Motherboard
ASUS showed off a unique motherboard concept part of its Republic of Gamers series, the ROG Immensity. This socket LGA-1366 motherboard comes with onboard graphics, using a discrete ATI Radeon HD 5000 series GPU with dedicated GDDR3 memory. While the Intel X58 Express + ICH10R chipset are very much there, the X58 is wired to a Lucid Hydra Engine chip, which drives both the PCI-Express 2.0 x16 slots. It is probably also connected to the ATI Radeon GPU, giving users the ability to stay connected to the on board GPU, while 3D graphics is accelerated from any graphics card plugged in to the PCI-E slots, of any make, and in any combination (including NVIDIA + ATI). The Hydra chip handles the load-balancing between the GPUs depending on their computation power and features available.
Apart from this unique feature, the ROG Immensity is designed for extreme overclocking, making use of an 8-phase PWM circuit with additional stabilizers and power conditioning using super-ML capacitors. Memory is powered by a 6-phase PWM circuit with its own power-conditioning super-ML capacitor. All ROG-exclusive features such as iROG and ROG-Connect are present. Connectivity features include SATA 3 Gb/s RAID, two SATA 6 Gb/s ports, USB 3.0, Bluetooth, gigabit Ethernet, and 8-channel audio. Four PCI-E x1 slots make for the rest of the expansion. For now ASUS chooses to call this a concept design, so it's uncertain whether it will release it to market any time soon.
