new iMac 27inch 3.4ghz i7

Hi all, new to these forums. Found it on a google search. Anyways, I lashed out today and bought a new iMac 27 inch. Did a custom order and got 3.4GHz i7 and 2GB graphics card. I opted for just the 4GB of ram tho.

I bought it because i want some landscape space (27 inch) and plenty of horsepower to do video, photo editing and web design related stuff.

Would 4GB be adequate do you think for the next 6mths? Or should I have bought more?

Thanks

I'd bump it up to 8gb, I've got that in mine and it's pretty snappy.

Don't pay $200 for 8gb from Apple, get it from some place like OWC or Crucial for about 1/3 the cost.

I've got the mid 2010 i5 machine, with way less GHz than you do and half the graphics card. Photo editing is no problem at all. And then I mean quite serious editing (average Photoshop documents are between 300mb and 1gb, works like a train).
Although sometimes having 8gb of ram sounds nice, it does a great job with 4gb already.
