Need Mac buying help...

[juliem888]

Okay I decided that I am switching to Mac, I own almost everything else apple has..lol

So I need your help please... I am looking at the all in one macs (the iMac).. Are they worth it? What specs would you suggest? I would like to run photoshop cs5, perhaps Lightroom etc.

I have googled and searched here, but most people have MacBooks, I don't want a laptop sorry mean notebook :-)

I am thinking of this model with upgrade to 8mb ram + upgrade to i7
3.1GHz Quad-Core Intel Core i5
2560 x 1440 resolution
4GB (two 2GB) memory
1TB hard drive1
AMD Radeon HD 6970M with 1GB
+ the time capsule (worth it?)
+ warranty (again worth it?)

Thanks ladies any suggestions would be greatly appreciated and if not the iMac why the macbookpro other than travelling with it?
(gotta love Christmas + birthday close together..lol)
