Would Indesign give me any faster screen drawing with a faster GPU? I have a Mac Pro at work that has the standard GT120 card in it and it seems much slower than my Windows 7 home system, which has a GTX 570. I was thinking of upgrading the GPU thinking that was what made the difference though it may be that my home machine has a 3930K CPU, 32GB of RAM and an SSD.
I have documents I work with that have several thousand pages with PDFs on each page. When I turn on high quality screen draw it is painfully slow on the Mac at work.
