Hi all, I have a dual 2.0 G5 with 2.5GB of ram but I have a puny ATI Radeon 9600 pro with 64MB of VRAM. Aperture runs o.k. but from what I've read performance would increase substantially if I had a better video card. I've seen all of the Apple recommended video cards, but I'm wondering if any of you know what the best "bang for the buck" video card would be. Specifically for the purpose of increasing performance in Aperture. Thanks.
