first off, i want to say im a long time reader first time poster 
I have a ATI x1400 gpu in my 1705 i purchased few months back... at the time i purchased, the only available gpu was the 1400...
i really want some more graphics power so i want to upgrade my graphics card...
i found on dells website how to take out the video card and how to put a new one in... BUT where can i purchase the card from? should i get a 7900 7800 6600 6800???
what are costs, and do i have to do any type of modding
all help is appreciated
