Re: nVidia vs. ATI
select 'desktop vga . . .' from the chart menu
scroll to the bottom and open the 'add a product' dropdown
add the 8800 gt
the ati 3800HD is the closest in terms of performance
or the ati x1900 xt cf

The reason I use ATI is I go for price/performance to a certain degree
rather than pure performance. I would not use ATI just to use it.
