When a wonderful 2.0GHz G5 (8G mem) failed. I moved the drives into a 1.8GHz G5 (2G mem) and am really surprised at what seems to be its lack of performance... just doing youtube stuff, even without enlarging the playback, it stutters every 3sec or so on playback. Making it larger makes it unwatchable. Is this the nature of the thing? or is there a problem, or wrong setting somewhere that's causing this?
You didn't specify the hardware exactly, but if the 2.0 was an "Early 2005" dual 2.0 and the 1.8 was an original single 1.8 there could be a quadruple whammy effect of half the CPUs, half the video card RAM, and 1/4 the actual RAM, and slower System bus.
You need to max out both the RAM and the video card on the new one. Hopefully you can move the RAM & video card from the dead 2.0 over to the 1.8 without issues. If the 1.8 is a single, you may be able to upgrade to a dual CPU, but that might be a lot of work and expense. I'd concentrate on the RAM and video card for now.
