What to look for in a Mac for video editing?

[sunkast]

Curious, how many shows and are they 1-2 hours a piece or all together? How many times a week?

List of our shows can be found here: http://www.guysfromqueens.com/showsongfq/

• AZ Show - 2 hours
• The News - 30 mins
• IJS - 1 hour
• WTT - 1 hour
• CH Show - 1 hour
• TNW - 1 hour
• FFA - 2 hours
• BBR - 1 hour
• TBT - 2 hours
• BTC - 1 hour
• IAIB Spotlight - 1 hour (bi-monthly)
• Picks of the week - 10 mins

Most shows are weekly with the occasional hiatus.

Plan is to learn Final Cut Pro to edit with. It can't be worse than the PC I have now. It does alright. But I'm looking to see if a Mac will help with the work load.
