hey everyone, i scored a sweet deal on a 12 core, 2.93 mac pro and i've spent the past week configuring it. it's a beast of computer now with an ssd boot drive, an ssd array as my FCP X scratch disk, and 64 gb of ram. here's the problem though, FCP X is still rather sluggish. when rendering, importing, etc, i can't get the machine to use more than 20% of the cpu. watching activity monitor shows that it's barely touching the ram or cpu. any thoughts?
