Any ideas / rumors / speculation on when OS X will have true 64-bit support for the G5's ?? i am looking to buy a Desktop for Audio to take some of the use off my powerbooks and turn them into mobile-only machines. also i need more processing power. I am contimplating whether to get a 1.25 - 1.4ghz G4 (upgraded) or a G5 1.6 or 1.8ghz. For the Audio applications that i use where Cache size is a big factor in performance, an upgraded 1.4ghz (2MB L3) would run just as well if not better than the single G5's currently available (i've researched some benchmarks using the applications i use). and also save me a few hundred dollars. IF OSX will go 64-bit say.. in the next 12 months, then obviously the G5 would be a better investment, but if not i'd have to go with a hyper G4 in the meantime and upgrade later. Also, what effect would a 64-bit OS X have on a 32-bit OS X application? any or none? If i have to wait for the applications themselves to be written for 64-bit before i see a performance boost, then i might as well just get a G4. Applications i use commonly are Reason 2.5, Ableton 3 (which isnt even altivec optimized yet), Cubase SX, Peak 4, Final Scratch 1.1.5, and would like to use Logic 6 in the future. thanks guys.
