It's pity that wine can't support same time 4Gb and 8Gb models.
If you have GLX_MESA_query_renderer Wine should report the correct amount of video memory, regardless of what's in gpu_description_table[]. Note though that how much of that's visible to the application depends on the selected Windows version and whether the application is 32-bit or 64-bit.
