HIS Radeon HD 5870 1024MB Gallery and Specs (2)
At the rear side of that rounded curve on the card we see two air intakes. The card is designed in such a manner that it will take in air from your PC and exhaust the heated air outside the PC. As always we recommend you to have a well ventilated PC with at least a 120mm intake and exhaust. Create some airflow fellas, really important.
All the way up front to the left you can see the two CrossfireX fingers / connectors. The HIS card is 100% reference based besides that sticker right there. The specifications are 100% the same as well:

And here we have the two cards all pimped out in our way too expensive test system. Looks good like a nice duo alright. Anyway, it is time to move onwards to some actual game benchmarking. But first let's peek at our test system.
