Boutique system builders usually stock both AMD and NVIDIA GPUs to appease both sides of the "which GPU is better argument," as you will always have customers who want both. It appears that the folks over at Origin PC have decided that stocking AMD GPUs is just not worth it anymore.
Citing "customer experiences" and "poor customer support" Origin PC has decided to stop offering AMD GPUs in their system builds as it has just became too much of a headache. With AMD just launching its new Radeon R series of GPUs, this new development has to be a crushing blow and shows that companies need more than new hardware to keep customers coming back.
This decision was based on a combination of many factors including customer experiences, GPU performance/drivers/stability, and requests from our support staff. Based on our 15+ years of experience building and selling award winning high-performance PCs, we strongly feel the best PC gaming experience is on NVIDIA GPUs.
