Video card advice

[treeves-1968]

I hope I am putting this in the right place. I built a custom system a few years ago for Revit modeling, 3ds Max modeling and rendering using V-Ray. I have been very happy with the system. Now it is looking like I really need to get Vantage so I can do some faster rendering and probably some animations. I will list specs below. My problem is my current video card wont do it. It only has 8gb and I have tried loading scenes into vantage back when I was getting it for free and it said I didnt have enough VRAM. My question I guess is how do you figure how big of a card I might need? After some "quick" looking on neweggs website, they have some RTX 40 series cards with 24GB, but they get really expensive. But if thats what I need to get then I guess thats how it is then. I thought before when I was looking into bigger cards you could get them for ~$800.00ish but these are close to $2,000! Thats a bit more than I was expecting. Anyone here have some knowledge they would care to share with me? Is there something in the file properties that will tell me how much memory a scene might require? Im not looking to buy this second, but want to start looking into it as my job is going to require it sooner rather than later. TIA
