Hi I bought a second hand PowerMac with a 1.8GHz DP, which came with the default ATI Radeon graphics card with 64 MB VRAM. I love the machine, works really nice with Leopard, especially when I upgraded my RAM to 4 GB. I mainly run the following apps on the mac: Office 2008 iWorks 08 iLife 08 - excluding Garage Adobe CS2 Macromedia Suite 8 Freeway Pro Adobe Lightroom I have two questions: 1. Will I benefit from a 128MB/256MB graphics card? 2. I have a slight problem with the crispness of the characters on the screen. Is this a sign of a faulty card or a dodgy monitor? Will a new card fix this problem?
