2. Graphics Card (GPU): Especially important for gaming or graphic-intensive tasks, a good GPU can significantly enhance performance. Check for dedicated graphics cards from NVIDIA or AMD that match your needs, whether for gaming, content creation, or professional applications.

• Good: NVIDIA GeForce RTX 3070 or AMD Radeon RX 6700 XT – These provide excellent performance for gaming at high resolutions and support for ray tracing and AI-driven features.
• Less Desirable: NVIDIA GeForce GTX 1650 or AMD Radeon RX 550 – Entry-level GPUs that are sufficient for casual gaming and multimedia, but may struggle with newer titles at higher settings.

3.RAM (Memory): Adequate RAM ensures smooth multitasking and responsiveness. Aim for at least 8GB for general use, 16GB for more demanding tasks like video editing or gaming, and consider upgrade options for future-proofing.

• Good: 16GB DDR4 3200MHz – Offers ample memory for multitasking, gaming, and content creation without bottlenecks.
• Less Desirable: 8GB DDR4 2400MHz – While still usable for basic tasks, may limit performance in demanding applications or future-proofing.

4. Storage Type and Capacity: Choose between fast SSDs (Solid State Drives) for quick boot times and application loading, or larger HDDs (Hard Disk Drives) for more affordable mass storage. Consider a combination of both for optimal performance and storage capacity.

• Good: 500GB NVMe SSD + 2TB HDD – Combines fast boot times and application loading with ample storage for games, media, and files.
• Less Desirable: 256GB SATA SSD or 1TB HDD – Limited storage capacity or slower read/write speeds, impacting overall system responsiveness and file management.

5. Form Factor and Build Quality: Depending on your needs, decide between desktop towers, compact PCs, or laptops. Ensure the build quality is robust, with good ventilation and easy access for upgrades.

• Good: Dell XPS Tower or ASUS ROG Strix Gaming Desktop – Well-built with good airflow, easy accessibility for upgrades, and sturdy construction.
• Less Desirable: Budget or unknown brand mini-towers – May lack upgrade options, have poor cooling, or use lower-quality materials impacting durability.

6. Connectivity and Ports: Evaluate the available ports such as USB (including USB-C for faster data transfer), HDMI, DisplayPort, and Ethernet. Consider your peripherals and external devices to ensure compatibility.

• Good: Multiple USB 3.1/3.2 Gen 2 ports, USB-C, HDMI 2.1, DisplayPort 1.4, and Gigabit Ethernet – Provides versatility for peripherals, high-speed data transfer, and connectivity options for monitors and networks.
• Less Desirable: Limited USB ports (especially older versions like USB 2.0), outdated video outputs (like VGA), and slower Ethernet connections (10/100 instead of Gigabit).

By focusing on these factors, you can make an informed decision when purchasing a new PC that best suits your specific needs and budget.
