"The Radeon HD 5770 GPUs ain't as hot as its predecessor. Still, HIS made sure that their Radeon HD 5770 are properly cooled by their IceQ5 cooler. Using Everest, we measured the GPU temperature, which turns out to be approximately 45 degrees Celsius during idle, and reaching 52 degrees Celsius on load.   For a mainstream graphics card, it's packed with great features including GDDR5 ram, an overclocked GPU, UV sensitive IceQ5 cooler, support for DX11 and Crossfire X, as well as ATI's Eyefinity." - Funky Kit

" This 5850 is one of the fastest pre-overclocked ATI 5850's you can buy.  I was very impressed with the 3DMark vantage score.  HIS have done a great job with the cooler and also the pricing.   Also you get Call of Duty Modern Warfare 2.  If you are looking for a very capable, quiet, ATI graphics card but do not want to shell out on a 5870 then this has to be the card for you." - Benchtech UK

"The HD5850 is a fantastic graphics card. HIS has taken the 5850 and replaced the cooling solution with an iCooler V model. These changes mean that this product runs cooler than a reference HD5850. The iCooler V Turbo model performed exceptionally well.  The HIS 5850 iCooler V Turbo model provides better performance than a 5850 clocked at reference speeds, and earns our “Worth Buying” award."- KitGuru "Worth Buying Award"

" The HIS IceQ 5 5770 Turbo has changed my perspective of PC gaming with a strict budget. While reviewing the HD 5770 IceQ  5 Turbo I have been extremely impressed. When I factored in that certain HD 5770 1 GB cards here in Canada were priced as low as $159 with free shipping it certainly opened my eyes. It made me realize that for roughly $600 we can build a good AMD gaming…" - KitGuru - Must Have Award
