I use 1gb with Photoshop7 here, didn't have quite a good experiance using 512mb on my older PC with other apps in the BG running, especially when you're working with 1024x768+ resolutions with multiple layers...
Unsure of whether or not it also becomes slower due to drawing operations when you get multiple layers with alpha transparency involved though.
