How do you think CS5 would run on my 3,1 MacBook? Specs as seen in my sig. Obviously, the GMA X3100 is my biggest bottleneck. I currently have CS3 installed, but I'd like to give my Adobe apps access to more RAM, which would require them to be 64-bit. Does anyone know if anything would not run at all? I mostly use Photoshop and AfterEffects, as well as some Illustrator. I'm most concerned with AfterEffects, and if it would either not run or run significantly slower, then it wouldn't be worth it. Any ideas?
