Everything else being equal, a faster processor will definitely make much more of a difference than a faster video card. In OS X, if you have less than 256 MB of physical RAM, you probably want to get yourself at least up to that level to minimize virtual memory use.Darcy wrote,Unfortunately, the GUI is *much* slower, and this creates the (incorrect) perception of general all-around sluggishness. Unfortunately, the slowness in GUI also extends somewhat to graphics apps (really, anything that involves screen redraws), so while most Photoshop filters are faster, scrolling, etc is slower. Hopefully this is something that will improve with time, and of course ever-faster hardware will make this less and less of a problem.You also made a similar comment in an earlier post.
Some years (?) ago I asked the list what would speed up Finale: faster processor or better video card. I never got a good answer on the latter, but I gather from your email that a better video card will speed up screen redraws, etc.
I have a G4/466 at home and a G4/533 at school, both running OS X 10.2.2. They come with a Rage Pro with 16 MB RAM. Would upping this make that much difference in my user experience?
But I'm confused about your statement that these G4s have a Rage Pro, since the G4s always shipped with a Rage 128, at minimum -- unless of course they aren't "real" G4s, but beige machines that have had their processors upgraded. If that's the case I would recommend putting a Radeon 7000 PCI in both machines. OS X support for the Rage Pro is dodgy at best, and 2D acceleration is often not supported. If you are mistaken about the type of video card you have -- if you have a real G4 with a Rage 128 or better -- than you won't see much improvement in 2D performance between the Rage 128 and the Radeon 7000, although the image quality is much better, IMO. (The main reason to get one of these cards is 3D performance -- the Radeon 7000 is over three times faster than the Rage 128.) Finally, if you have a real G4 with an AGP slot for the graphics card (the AGP slot was introduced with the second generation of G4s) and your current video card has less than 32 MB of VRAM, you should *definitely* upgrade to a Radeon 9000 AGP so you can take advantage of Quartz Extreme.
