I've been doing a lot of reading regarding 10.5's high resolution interface, and I am wondering if my lowly 64mb 9600 in my G5 can handle it? Truthfully, I could care less about GUI bling, but if it is going to slow things down on my machine, well, then it does matter to me. I've never had a problem with my machine before, but I plan on keeping it for a few more years. If I need to upgrade, I'd like to find one that will last me until 10.6 arrives since that is when I plan on replacing my machine. PowerMac G5 Dual 1.8ghz, Agp 8x/Pro slot 20" Cinema Display (DVI) Budget, somewhere around $200-$250, although I'd prefer something closer to $150, so I can get another 1-2GB of RAM with the savings. Thanks in advance.
