I may not be too much help to many of you but I have done a fair bit of research on this item due to unrelated issues so I will save you the trouble.
This card worked well while it lasted but because I had a bad power supply it got fried. Not the card's fault but what can be said of it is that it gave me acceptable framerates, 20-30 fps, on Crysis with high settings and 2x anti aliasing.
However, because I was having overheating issues with this card because of the power supply, I researched general overheating problems with this Asus CuCore Radeon HD 5770. This card is built on a 40nm process, which means that it should run cooler than other cards that have a larger build process. Yet people who didn't have my power supply problems were reporting higher than normal temperatures.
The tech savvy ones took off the cooler to find that there were dimples and even waves in the copper surface that is used to transfer heat from the graphics chip to the heatsink and fan. When I took off my cooler I found circular grooves on the copper surface so this isn't just an isolated issue. Apparently the build quality of the CuCore cooler is less than stellar.
Now these temperatures are not going to fry the card. GPUs can handle nearly 100 degrees Celsius before they begin to see problems and the reports I've read said temps were no higher than 86 degrees. However, better cooled cards will rarely go over 75 degrees so you see the issue. If that still seems too high for you I suggest getting the Sapphire Vapor-X for thirty dollars more. You would have to spend that same amount to get an aftermarket cooler for the Card anyway.
If 10 degrees Celsius and the trouble of installing an aftermarket card are too much for you, I suggest passing on this card due to poor build quality.Get more detail about Asus ATI Radeon CuCore HD5770 1 GB DDR5 PCI-Express Graphics Card EAH5770 CUCORE/2DI/1GD5.
