aahh score man! if the machine is too powerful then i strongly would suggest the i7 iMacs (i have one and LOVE it)! they are very powerful machines at the moment - fine for consumer video editing thats for sureThe one on the left doesn't do much. Its an old G5 that a buddy of mine was going to eWaste since he got a new Mac Pro. I took it from him and got it working. The wife just surs the web, checks email, and does photo stuff on it.
The Mac Pro on the right is mine and is complete over kill for me. I bought it with plans to do some video editing and heavy photo editing but have not done much of it yet. With our new baby coming I'm sure that will change a bit but the machine will still be overkill. I only bought it since I had a Developer buddy who was getting hooked up on a deal and he added a machine for me. The 30inch ACD I bought used from someone on here for $1000 I think. I love it!
goodluck with the baby! when is it due?
