I currently have a Dual Gig G4 Quicksilver Tower that's maxed out (except for the original nVidia Geforce 4 MX card w/64 MB of Vram) running OS X 10.3.9. I do alot of intensive Photoshop, Illustrator, Bryce 3D. I'm really chomping at the bit to get at least a G5 because the 1.5 GB of ram is just not cutting it. Will a Dual 2.0 G5 be enough of a noticeable power difference over my current Dual 1Gig G4 ?? Or should I look at the Dual 2.3 G5 as a minimum ?? I'd really like to stay with a G5 PPC because of the price and also because I have older versions of Bryce that I must keep and have to be able to run in "Classic" which is impossible with the new intels. Not to mention my other graphics programs which are PPC that would be obsoleted if I were to get the new Intel Mac Pro (which I definitely can't afford anyway). Some of the files that I work on in Photoshop are up to 100 MB in size and can occasionally can be up to 200 MB in size (rendered Bryce Images). I had an 83 MB size file open last night and tried to just use the "Zig Zag" filter in Photoshop 7 and it told me that it "cannot complete the Zig Zag command because of not enough memory" (ram). And that was with no other programs open at all with 1.5 GB of ram in 10.3.9. How is that possible ?? I'm wondering if it was referring to system ram or does it utilize ram from the Graphics Card at all for using filters ?? I also have plenty of Hard Drive space for the cache so that shouldn't be an issue (on a seperate HD than the OS). Is that particular Photoshop filter really that ram hungry with that kind of file size ?? Or is my nVidia card with just 64 MB of ram playing any part in that ?? Will getting a Geforce 4 Ti card w/128 MB of ram alleviate any of these issues or is my G4 just getting too long in the tooth....especially with the limited system bus of 133 Mhz and 1.5 GB ram limitation ? (which I suspect it is). Anyways, I'm hoping that maybe a Dual 2.0 GB G5 (with at least 4 GB of ram) would be enough of a jump from what I currently have to satisfy me for a couple more years. Anyone out there with some insight and/or suggestions ???
