I am looking to get a dell xps 8100 with the following specs: core i7 880 1 terabyte hard drive Windows 7 Professional 64-bit 6 gb 1333Mhz RAM Basic Keyboard (included) Laser Mouse (included) *Graphics Card* Microsoft Office Home and Business 2010 I don't know a whole lot about ati graphics cards so I was looking for a little help on them. I do a lot of HD video editing and rendering. I will use Premiere Pro CS5 when I get my new computer. I will also take any suggestions for a graphics card. My goal is to spend under 1500 including tax. I realize that it may not be possible to spend that little for everything I want (so I may be willing to go over that price). I am wondering which graphics card is best for what I do (and yes I know the gtx 460 is not officially supported for CS5, I don't remember if the 5770 is either). I don't play many games. Please could someone tell me what is best?
