Maybe I'm missing something and it's just the sales person in me...
...but HOW THE H*** CAN ANYONE GIVE ANY ADVICE without first asking what OP is going to do with the machine??????
Well I guess it's easy to give ANY advice, but not relevant advice...sorry but it just "frosts my soul" (as my cousin in Chicago likes to say), that people don't ask/just tell...
If the machine is limited to single photo processing of RAW still images the whole machine is over the top...a simple out of the box/over the counter $600 i7-860 PC will comfortably handle such tasks...
If batch processing and video editing is in use then I can understand the need for such high end gear...
just sayin'
Easy Kit. Thank you for your concern. Yes my wife will be using it mainly for photo processing and demanding games like solitaire. 
My friend, (Que southern accent) I'm an American. No such thing as too rich, too thin, too much chocolate or too much horse power. Bigger is always better. Yes it may be a waste but if it keeps my wife happy, I'm happy,
Have a Merry Christmas.

and if that's the case i would get several hd of the samsung f3 for backup. pair them with hdd dock and you're all set. oh, and of course a nice IPS monitor with calibrator if you don't have one already. nice system and good luck....
