We’ve literally loved everything about the HD 4850 since its release. The only thing that worried me was the high temperatures coming out from behind the card. While the stock single slot cooler is an excellent choice, it simply isn’t going to do as good a job as dual slot coolers with bigger fans.

Sapphire has not only chosen to include aftermarket cooling on the card, but also to take it a step further by overclocking the bad boy. With two in hand today, we will be looking at both single and Crossfire performance. Before we get into that, though, let’s have a quick look at the package and the actual cards.
