Does more Graphics Card Memory increase performance?

[craftycurate]

Hi ...

I have recently had a graphics card replaced under warranty - same model, but they've given me a 512 MB model instead of my old 256MB one. (nVidia Go 7900 GS)

Will this lead to increased performance with R3, and if so, under what circumstances?

e.g. overall performance increase? Or using certain shader-based effects? Or using DXV encoded clips? I guess it depends what is making use of texture memory.

Thanks
