For gaming computer builds, what component is essential besides multicore processors and high-end GPUs?

  1. High-end cooling

  2. Cassette tape drive

  3. Dial-up modem

  4. Rack chassis

The correct answer is: High-end cooling

When building a gaming computer, it is essential to have a high-end processor and GPU for optimal performance. However, those components generate a lot of heat, so it is crucial to have a high-end cooling system to keep the computer running smoothly. Options B, C, and D are all incorrect as they do not directly impact the performance or cooling of a gaming computer. A cassette tape drive and dial-up modem are outdated and not necessary for gaming, while a rack chassis is used for server systems, not gaming computers. Therefore, the correct answer is A, high-end cooling.
