A:Answer greyseal,
Thank you for your interest!
The video card has 8GB of GDDR6 memory.
As to the noise level, this system would tend to be quieter than some, due in part to the Liquid Cooling system for the CPU, which replaces the air cooler that would otherwise be used. One of the purposes of Liquid Cooling is to reduce noise.
This being said, there are still several fans in the PC, to circulate air throughout the chassis and across the Liquid Cooling radiator, to remove heat from the system, and there would at times - as with any system with fans - be some noise from them. Whether or not that noise would be considered loud or noisy, would be relative for any given individual, and would depend on several factors, such as the level of ambient sound in the environment, whether or not headphones were being used, personal sound sensitivity, etc.
