The ultimate question!

To all the video experts out there - which would you recommend? I am planning to get into video work. At present I have a PC and have been using it for small projects. However, it has got to the point where I need to upgrade my current system. I reckon it will cost about £800-£1,000 to get everything that I need.

I have been going down the route of looking at an AMD Athlon 64x2 Dual Core 3800+ processor, and compatible motherboard etc (probably ASUS). However, recent press about Macs and the Intel chip are making me think again.

A number of years ago I heard someone that Apple Macs were better for video editing - does anyone know if that is actually correct?

If I'm going to spend almost £1,000 I would like to get a good system and so would value your opinions/advice? Which is the better option - Mac or PC?

As a side note, are Macs as easily upgraded as PCs?

Many thanks.
