Reanimation_LP said:Since Tigers' Core Imaging is going to require 64 MB minimum, I'd personally go with the 128 MB. Your gonna want all the VRAM you can get, plus then, dont forget, you CANT upgrade the VRAM. So you might as well drop the extra 100 and get the extra VRAM. Plus, 128MB of VRAM will make Quartz Extreme and Expose run smoothly on a 20" or higher monitor.
Just like the Mac miniJigglelicious said:If you plan to use ONLY the external 20" monitor with your Powerbook, then 64mb will suffice. However, if you plan to operate both the internal 15" screen and the external display at the same time, then that 64mb will be split in half, and 32mb WILL be choppy on the 20" cinema display.
