Thanks for the replies!
He won't be playing any games (COD4 etc...) and no Blu-Ray playback.
Mostly it'll be used for multitasking and he won't be upgrading for at least 2-3 years. That's why I want to built him nice system that will last for some time.
I've modifed setups per theAnimal's suggestion.High-End Modifedhttp://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=11042506Low-End Modifedhttp://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=11042266
I've left 9500GT because I think it'll be o.k. "in case" he decides to play some game (Please suggest anything better).
Will 4GB of memory be fully used in Vista? or do I need 64Bit. I do not want 64Bit version do to driver issue with printers etc.
After modifying original version now even High-End option is exacty within his budget and that's inc. shipping.
Please feel free to suggest.
