First of all, this game is crack...it's so addicting. And it runs relatively well on my Mac, but I'd like to get it at something up over 30-35fps in all cases (except, of course, in the cities...I know that's a big performance hit when 8million people are around). I'm usually hovering around 25fps with all the sliders set to low, and in battle it drops around 20. Here's what I have: Digital Audio upgraded with a single 1.8GHz GigaDesigns G4 1.5GB PC133 Radeon 8500 The Radeon 8500 is a flashed card, so I'm not afraid of modding a PC video card if that's what it takes. I've been looking at the Radeon 9800 and wondering if it would help framerates. If not, I could look at selling the system and buying an iMac G5...but for now, the 9800 looks like a relatively cost-effective endeavor. Does anyone have a G4 system that they play WoW on? And if so, have you upgraded it? What helped performance?
