No. Furmark is basically an overheating test. And it is throttled down in AMD- and Nvidia drivers to prevent overheating. The FF14 benchmark however is a good memory- or "did i undervolt/overclock too much"-test. I know one case, that a guy undervolted his GPU. All games but the FF14 benchmark ran stable. He undervolted the GPU a little bit less and it also worked with the FF14 benchmark. The FF14 spoiled a semi stable system.
