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

1. Purchase a non-identical video card

2. Install additional RAM

3. Use two identical video cards

4. Download drivers from different manufacturers

The correct answer is: Use two identical video cards

When configuring a system to use Crossfire, it is essential to use two identical video cards. Crossfire technology, developed by AMD, is designed to allow multiple graphics cards to work together to improve rendering performance. For optimal compatibility and performance, both graphics cards should be the same model and ideally from the same manufacturer, as this ensures that they can communicate effectively and share resources seamlessly. Using identical cards helps to prevent any discrepancies in performance or functionality that could arise from differences in specifications, memory size, and core architecture. This requirement does not apply to non-identical video cards or those from different manufacturers, as they may not work together properly or could lead to suboptimal performance. Similarly, additional RAM may improve overall system performance, but it is not a requirement specifically tied to Crossfire functionality.
