Why Water?
Liquid cooling takes advantage of the key features that a larger radiator offers compared to local sinks, with the added benefit that the radiator can often be mounted in a cooler air stream.
That explains why a large radiator sits at the front of most automobiles, but in the case of overclocking, complexity and inconvenience have limited the number of liquid-cooling applications in PCs. Most liquid cooling systems focus on the CPU, since adding other components to the loop makes servicing a nightmare. In particular, removing a liquid cooling system from graphics cards requires extreme caution and plenty of extra time to drain the system, which must then be refilled and re-purged (to remove air from the water lines) before it can be used again. This could easily turn five minutes of diagnostic work into a one-hour ordeal–and that’s if you know what you’re doing.

Faster And Cheaper
A manufacturing process shrink is a lot to get excited about for both vendors and their customers, as the change normally leads to increased performance and efficiency, while reducing production cost by increasing the number of units produced per wafer. But the eventual benefit to design firms often comes at a huge up-front cost, since significant alterations normally result in bugs that need to be fixed before a full production run can begin. Each test run costs hundreds of thousands of dollars, so it pays to get things right the first or second time. Production delays are an even costlier problem when new architecture is involved, which is why Nvidia normally updates its current products before introducing any new ones.
Today’s updated product, the GeForce GTX 285, makes the typical promises of improved performance and efficiency compared to the GeForce GTX 280 on which it is based. Let’s take a quick look at how it compares to other high-end solutions. (more…)

EVGA GTX285 FTW its fate (For The Win) Edition and the big feature of this card is its operating frequencies, simply the highest in the market for this type of card!
The core is then clocked at 720 MHz to 648 MHz against the standard map, as the shaders spend 1476 MHz to 1620 MHz memory while it is good to 292 MHz from 2480 to 2772 MHz!
The secret of this card is without doubt an operating voltage higher, probably 1.2 V 1.15 V against the original which would explain certification also attractive.
Do not forget that despite this factory overclocking rather convincing, EVGA will allow you to go further …
Indeed, the software EVGA Voltage Tuner “which is apparently imminent exit, you will no more and no less than change the operating voltage of GPU card on the fly as did Gigabyte on the card you NX88GT512HP .

ATI quietly preparing a reply to GTX285 and GTX295 who themselves were a response to the 4870 X2 which was first place for performance over several months.
We learn that stamped samples RV740 and RV790 would be outstanding, and yet it is only a simple die shrink to 40 nm, thereby understand pasted a copy but with a more detailed engraving and can be frequency revised upwards.
ATI will be like with nVidia GT200b, with the key to reduced consumption and increased frequency minimal but nothing transcendent.
These chips probably will replace the current HD 4850 and 4870 pending the release of the RV870 which will bring a new batch of much consequence. The launch date is set for March (who said Cebit).

MSI is proud to present its latest N295 GTX and Geforce 285 GTX series of graphics card, the MSI N295GTX-SLI is able to optimize the design M2D1792 two GPUs on one card. MSI N295GTX series consists of two 55nm GeForce ™ GTX 200 GPU with a capacity of processing 480 and 896-bit bandwidth memory, providing 50% moderately improved the GeForce ™ GTX 280 in a real game reference. MSI N295GTX and N285GTX series graphics card is included with the game Rainbow Six Vegas 2, “which scored a 8.2 on the popular Web site www.ign.com games.
MSI N285GTX OC version
In addition to the standard N295GTX and N285GTX graphics cards, MSI introduces N285GTX-T2D1G-OC version, the GPU overclocked to 680MHz, shader to 1476 MHz and 2500 MHz memory overclocked. (more…)
