Both manufacturers AMD and nVidia have issues with their GPU's/Software/Drivers... And both have their individual quirks.
nVidia for example is not as good as AMD when it comes to triple-monitor display support... Specifically there is some odd display sleep behaviour on nVidia triple monitor systems that just doesn't happen with AMD.
I suggest any individual not to buy into the fervent recommendations of the masses and actually look into these (expensive) components before hitting that buy button... And specifically look into how these cards handle in your specific use-case scenarios. - Read some reviews.
Everyone plays different games, everyone uses these parts for different uses. (I.E. Transcode/Decoding/Encoding/Compute/Modelling etc') - So one persons usage is not going to be representative of the next persons.
If you can save some cash by going with a different company, then all the power to you.
