Crossfire performance in Vista with Catalyst 8.7

Earlier this week, Catalyst 8.7 went live on the AMD server, so we thought we would check it out, and report on 8.7's performance. This Catalyst release was fairly major as it was the first to support ATI's newest HD 4000 series video cards. For this brief article, we had two main goals: first off, to see how much, if any, performance gains were made for a HD 3870 going from Catalyst 8.6 to 8.7; and second, to see what levels of performance CrossFireX setups using multiple HD 4000 could offer.
