I have a 450Mhz G3 B&W with the stock 16MB pci video card. Would an upgraded (32 or 64MB) card speed up rendering within Tiger? Specifically the genie effect when minimizing windows(right now its ok, but looks choppy)? Also when using expose, while it is fast, it is choppy. Also my current card doenst support quartz extreme, is this a huge benefit in appearance or not? Thanks!
