Hardware Unboxed uncovered issues in an handful of titles that are consoles developed with close to 16GB of VRAM.
HOWEVER, it is not the norm and it is HARDLY making games UNPLAYABLE at 1080p.
FACT - Techpower numbers are showing mere percents in both 1% low and Average framerates at 1440p! So stop getting brainwashed and making the generalization that games are unplayable with 8GB of VRAM, because they are not unplayable.
FACT - If you are buying a 8GB GPU, you already making a concession on the price because you will make concessions on the fidelity also. You will likely not play games at max settings anyway!
FACT - If you are using upscaling, this become an even lesser issue because your are running the games at lower resolutions anyway.
You are the one obviously missing the point. This is a 60 class card, it is the entry level of the gaming GPUs. I am fine with a 8GB version because it is enough at 1080p.
