What is the appropriate Video card Memory for a Windows computer (xeon 12 cores) with 2 display monitors: a 4k/60Hz (100% size)and a 1440p monitor? Would 2GB video memory be enough? I have a Nvidia gtx 1050 - 2 GB card (small footprint). Should I upgrade to a beefier card, 4gb or even more? I run Cubase 10 and Vienna Ens pro only.
