Hey guys! So i've got a Mac Pro 1,1 , still chugs along nicely however curiosity got the better of me. The machine is currently purposed with moving tape content (DV, MiniDV etc) to DVD and at the moment it takes about 2hrs per tape (1hr to get it off the tape, a further hour for iMovie to export it) and then a further 1.5hours for iDVD to burn the DVD. I'm wondering if theres anything i can do to perhaps speed this up? I cant seem to find any solid information on what iMovie and iDVD use when they handle video, some have said CPU and others say GPU so im not sure which to upgrade, or if both would need upgrading? The system has 7GB 667MHz DDR2 FB RAM, 2 Dual Core 2GHz Xenon Processors and the stock GPU which is a Nvidia 7300GT and OSX Lion 10.7.5. If CPU upgrading is the way to go, whats the fastest CPUs i can get which i just install and go? (Since i've heard its possible to install some processors by flashing to a 2,1 ROM, i dont want to do this. Yet anyway.) If GPU upgrade is the way to go, what would a better card be? My budget on a GPU isnt infinate, ideally dont want to go over £100 BUT will take any and all suggestions into consideration Not too fussed if its a PC card either since i just read another thread here that says PC cards can be supported with the aid of web drivers (Well, Nvidia ones at least) and im not fussy if i cant have the boot screen. Thanks in advance for any information guys!
