You don't want to go overboard on the video front, not without considering the CPU. I have a flashed 9800 Pro in my DA and performance in even the most basic tests is pretty embarassing (In the OpenGL test in Xbench, for example. my GMA950 MacBook scores 8 times higher and my B&W G3 with its PCI Rage 128 only scres 18fps less) because the 733Mhz Quicksilver CPU I have in it simply can't feed the card fast enough. The card achieves what I bought it for (decent Core Image/Quartz Extreme support) but it's a bit disappointing that I can't get some gaming done on the side with it. I'm thinking awful serious about getting one of those aftermarket G4 upgrade CPUs, something in the order of 1.4-1.6GHz, but that won't happen until after I've maxed out the RAM.
