Hi everybody. I just recently picked up a PowerMac G5 mostly for use with FCP and After Affects CS4. I was wondering what some of you may suggest to make a bit quicker with the rendering and loading of files... Just after a quick first start up I've noticed quite a bit of lag in editing - choppy playback and what not. The machine is running OS X 10.5.8 Heres a profile of the machine: - 4 x 2.5 GHz PowerPC G5 - 8.5 GB DDR2 SDRAM - NVIDIA GeForce 6600 I've already started looking at graphics upgrades and hoping that the ATI RADEON X1900 G5 Mac graphics adapter, 256MB - GDDR3 SDramter will solve the playback issues. I've also looked at installing an airport card as well as a bluetooth card, any suggestions on these will be very helpful as well. If any other information is needed to provide other suggestions just let me know.
