Most computer hardware enthusiasts and gamers are familiar with EVGA. They are an add-in-board partner for video cards based on NVIDIA GPUs in North America. EVGA also manufactures motherboards, and has models based on NVIDIA's nForce 680i chipset for Intel Socket 775 processors, and NVIDIA's nForce 590 chipset for AMD Socket AM2 processors. They are one of the few manufacturers offering lifetime warranties on video cards, and they are currently the only company offering a step up program on video cards. This allows customers to upgrade and exchange a video card at a significant discount if the upgrade is done within 90 days of the original purchase.
