A graphics card should fit your software, your monitor and your existing computer. Buying by memory capacity alone can lead to a poor match. This graphics card buying guide helps you compare the Zotac and Asus ranges at Richcom in Sri Lanka.
Compare the current Graphics Cards range and prices in Sri Lanka. Use this guide to decide what to check, then read the complete specification on your chosen listing.
Graphics Card Buying Guide: Start with the workload
For gaming, identify your display resolution and the games you actually play. For creative work, check the application developer’s requirements for GPU support and graphics memory. A card with more memory is not automatically faster in every task. Compare the complete model and use independent workload benchmarks when performance is the deciding factor.
Make sure the card fits the computer
Check the motherboard slot, case clearance, card thickness and space around nearby expansion cards. The power supply must meet the exact card’s requirements and provide the correct power connectors. Connector shape alone is not enough to establish electrical compatibility. Read the card maker’s installation guidance before choosing any power adapter.
Treat each listed model as a separate choice
The current examples include Zotac RTX 3060, RTX 3080 and RTX 3080 Ti models. Their cooling design, dimensions and power needs differ. Compare Asus and Zotac models using the precise model code rather than assuming all cards with the same GPU have identical fittings. Check the display outputs and warranty on the product you order.
