4.9/10verdict: skip

This is a 1080p card for small gaming, media or general-purpose builds where a cool, quiet GPU matters more than raw speed. It suits buyers whose power supply has no spare PCIe cables, because the card has no external power connector. It is a poor fit for anyone who needs more than 6GB of video memory.
