I ordered a 1.6 for video/audio editing. Haven't received it yet, but I think it will be fine. Most editing is done in our edit suite where we have p4 3.+ and xeon dual systems. But in the field, I've read there's only about a 5% differance between the M1.6 and M2.0, so it isn't worth the extra to me. More importantly is 1gig+ of ram and a good video card with seperate mem. So, the 1.8 should do fine.... don't expect real time rendering though! But if you use a well written app like Vegas, you won't have any problem. Vegas even works on PIIIs!!
