I upgraded my 9600 pro 64MB to a 9650 256MB and man what a difference a little bit of video ram makes. I was going to get an x800 but decided not to drop that much money into a video card. I won the 9650 off ebay for 30 bucks shipped. I can play quake 4 full settings and 2x anti aliasing at 1280x1024 with wonderful framerates. What graphics card do you have in your mac and how does it perform??
