I just got Starcraft 2 today. So I finally see where this 512 vs 256 mb is paying off.
256 mb users are forced to use texture quality on medium while the others can set it on high. However, I don't see any difference between medium and high texture quality though.
Now here is the interesting part. I get the same fps with texture quality on medium or on high. So texture quality is not taxing the GPU that much. Meaning, with 1 Gb of VRAM, this 330 can run texture quality on Ultra.
