Upgrading an older PC with a used CPU and GPU improves gaming performance on a budget

A budget-constrained PC experiencing stuttering and graphical artifacts in Fortnite was successfully upgraded by replacing the Intel i5-6400 CPU with an i7-7700 and the AMD Radeon RX 570 GPU with an NVIDIA RTX 2060. These upgrades, sourced from the used market for approximately $84 to $158 USD depending on the acquisition method, significantly improved performance. The system, which also features 16GB of DDR4 memory, a Corsair VS550 power supply, and a 250GB SSD, was further optimized through BIOS updates, Windows power setting adjustments, and undervolting the new GPU. The undervolting process reduced power consumption by 50 watts without sacrificing performance. The case, which lacks adequate intake ventilation, was found to be a significant thermal bottleneck. Removing the side panel during high-load scenarios reduced GPU temperatures from 81°C to 73°C, leading to the recommendation that the panel remain off during gaming sessions. The final configuration provides a smooth, playable experience in Fortnite at 1080p, even with high settings, demonstrating that older hardware can be revitalized with strategic, low-cost upgrades.

Replacing the i5-6400 with an i7-7700 and the RX 570 with an RTX 2060 significantly improved Fortnite gaming performance. Undervolting the RTX 2060 reduced power consumption by 50 watts while maintaining consistent performance levels.

The case's lack of intake ventilation caused thermal throttling, which was mitigated by removing the side panel. Removing the side panel during high-load scenarios lowered GPU temperatures from 81°C to 73°C.

Updating the motherboard BIOS was essential to ensure compatibility with the 7th-generation Intel CPU. The system's 16GB of DDR4 memory and 250GB SSD were retained as they remained sufficient for the intended use case.
