Calculate video RAM quantity need in 3D... how?
I knew easily how to compute 2D need, but I have in my back of mind wanting to figure 3D numbers. Recently I read the relation of 3D to 64/128/256/512... is similar to 2D to 1/2/4/8 instead of using it like GFX cache. Anyhow here is my concern.
I had only monitors going 1024x768 at max, I have no plan to upgrade those, is 128mb enough to use? Even for cards like 7800 or 6800.
The 3D is Direct3D as in the DirectX games.

128mb might be enough if the bus is only 128-bit. You might consider a 256mb card on a 128-bit bus...with ddr3 speeds, that is about the max I would use. If you wanted more than 256mb ram, then you would need a wider bus in order to notice a difference anyway. One thing to note, though, the 7800 and 6800 models with 128mb will tend to have slower chipsets and fewer pixel pipes than their 256mb brethren.
