Besides the Founders Edition, there are also a variety of aftermarket cards, referred to as "custom cards" by Nvidia. The graphics chip is taken from Nvidia and parts of the card are modified according to the company's specifications. Such modifications include: clock speeds, fans, heat sinks, connectors, and aesthetics. Such aftermarket cards tend to perform better than Nvidia's in-house cards, but such increased performance comes with tradeoffs in temperature and power consumption. Manufacturers include: Gigabyte, MSI, ZOTAC, Asus, EVGA, INNO3D.
