HIS HD 5870 iCooler V Turbo

Another customized HD 5870, this time from HIS. Interestingly, the memory comes at 1225MHz stock, but doesn't really do that much more than every other card out there when overclocked manually (1370MHz)

... In addition to what the reference design offers, HIS has bumped the clock speeds of their card by 25 MHz on the core and memory. 25 MHz doesn't sound like much, and it isn't. In our testing we saw a performance increase of 1-2%, depending on the resolution, something that is not significant, no matter how you look at it. If you are willing to do some manual work though, you can easily overclock the card in the 950+ MHz range with over 1350 MHz on the memory ...
