Ok, I'm seriously considering getting a new 15" PowerBook G4 in the next few weeks. I have only one dilemma: which VRAM option to get. I do not plan on hooking up my PowerBook to a 30" Apple Cinema Display, but I do want the extra graphics processing capability. I do a lot of video rendering in iMovie and Final Cut Express, as well as DVD encoding in iDVD. I'm planning on buying Photoshop soon too.....will the extra $$ for the 128MB of RAM make a big difference? Do Xbench scores differ on the 64MB versus the 128MB VRAM option? Also, if I get the 128MB option, will I have two DVI ports on my PowerBook (Dual-link DVI, according to Apple's website). Thank you!
