Which of the following will be necessary when configuring a system to use Crossfire?

Purchase a non-identical video card
Install additional RAM
Use two identical video cards
Download drivers from different manufacturers

The correct answer is: Use two identical video cards

Using two identical video cards is essential for configuring a system to utilize Crossfire. Crossfire is a technology developed by AMD that allows two or more graphics cards to work together to improve performance in rendering graphics. For this setup to function smoothly and effectively, the video cards must have the same specifications, such as GPU architecture, memory type, and frame buffer size. This ensures that they can communicate efficiently and work in sync to deliver enhanced graphics performance. Having identical video cards allows for better load balancing and minimizes issues related to compatibility and performance bottlenecks that could occur if different models or specifications were used. This requirement ensures that the system can leverage the full capabilities of both cards without discrepancies that could hinder performance.
