These 2 companies are out there for a long time, creating end game GPUs and CPUs. Some people might say the Nvidia's quality is better and you get more for your money, and Nvidia is also leading in sales and such. Although Nvidia seems to have most of the costumers, AMD offers the same products for cheaper but I've seen a lot of people complaining about their quality. I myself had experience with both companies (had the HD5770 from AMD and now i'm using the GTX 960 G1 gaming from Nvidia) Both were great for me so far and haven't had any problems. Which company do you guys prefer?
