  • newegg Ultra Durable VGA Ultra Durable VGA card provides dramatic cooling effect on lowering both GPU and memory temperature by doubling the copper inner layer of PCB, resulting in 5% to 10% lower GPU temperature. Ultra Durable VGA card reduces voltage ripples in normal and transient state, thus effectively lowers noises and achieves 10% to 30% increase in overclocking capability. Ultra Durable VGA board allows more bandwidth for electron passage and reduces circuit impedance. The less circuit impedance, the more stable flow of current which can effectively improve power efficiency, lowering power switching loss by 10% to 30%.

Making a believer out of a skeptic

Pros: Silent, well-built, effective, looks totally awesome

Cons: A bit large even for a mid-ATX tower. 10.8" long means I had to buy mounting brackets for my hard drives to slot into my 5.25 bays since this card would have easily backed right up to the edge of the HDD mounting area leaving no room for the actual drive or any connections

Overall Review: Even though I spent an extra $15 on brackets, I'm very pleasantly surprised with this card. It boasts much more gaming power for the price than my old 5770 Juniper and does so whilst completely silent. I'm no longer having to boost my bass on my speakers just to cover the unmistakable hum of a GPU fan working really hard. I wasn't too sure about a fan-less GPU - even if it is 2 series behind the top of the line ... this card has made me a resolute believer.

5/ 5

Pros: The obvious: performs like a champ, completely silent, looks seriously industrial. Received it at work and it made quite a stir among the geeks.

Cons: The Gigabyte label is upside down when viewed through the window of my Antec case. Apart from that, being huge would be a con if it didn't look so good doing it.

Mixed

Comments: An earlier review points to having the same problem with the black border. There was some suspicion that it was the monitor. Given my experience, where there was no border and no problems with the background (but I had other problems), the monitor was not the issue. It's when I upgraded Catalyst (rev 881) that I developed the same border problem.

My double-buffer / z-plane problem seems to be resolved with the Catalyst upgrade. But the loss of screen real estate and the lack of a nice background are now really annoying. Overall this was a functional step forward, but two aesthetic steps backwards.

Not a lot of choices for fanless GPUs that are multi-headed and have some decent graphics horsepower. I'm going to suck it up for now, but have my eye out for a new graphics card. Maybe Gigabyte / ATI can fix this sooner than later?

Very Happy

Pros: Noiseless
Plays all games I've tried including the Dirt3 that came with it excellent.

Cons: Power Color makes a passive 6850 I would have bought had I known at the time.

Overall Review: I am knew to video games but I knew that I did not want to hear a card fan and other cooling fans that I've heard on other peoples machines. Also I did have a pc in the past that I upgraded with a graphics card with a fan that died after two years and ended up using the onboard vga. This hopefully will last until the rest of my machine is outdated.
Measure before you buy, I had to do a little case modification to a brand new HP Pavillion but it still looks right at home in my office.

Best Passive Cooling Card

Comments: Get this card if you have a big enough tower to place it in. Never ever had I seen such a huge Graphic Card in my life.
