When choosing the best graphics card, consider factors such as your budget, the types of games or applications you plan to run, the resolution and refresh rate of your monitor, power supply compatibility, and whether you need features like ray tracing or VR support.

VRAM (Video Random Access Memory) is crucial for storing image data that the GPU needs to render graphics. More VRAM allows for higher resolutions and more detailed textures. For gaming at 1080p, 4GB to 6GB is typically sufficient, while 8GB or more is recommended for 4K gaming or professional graphic design work.

Integrated graphics are built into the CPU and share memory with it, making them suitable for basic tasks like web browsing and office applications. Dedicated graphics cards have their own GPU and memory, offering significantly better performance for gaming, video editing, and other graphically intensive tasks.

Cooling is essential for maintaining optimal performance and longevity of a graphics card. High temperatures can lead to thermal throttling, where the GPU reduces its speed to prevent overheating. Effective cooling solutions like fans or liquid cooling help maintain stable temperatures during intensive tasks.

Yes, using multiple graphics cards in a setup known as SLI (NVIDIA) or CrossFire (AMD) can enhance performance by splitting workloads across GPUs. However, not all games or applications support multi-GPU configurations, and they require a compatible motherboard and sufficient power supply.
