Hey all, I know pretty much nothing about graphics cards and I am thinking about buying a new computer. It comes with an option of 3 cards: 1. '8800GT 512MB SLI DDR3' 2. 'NVIDIA 8600GT SLI 1024 MB' 3. 'NVIDIA 9600GT 1024MB SONIC DDR3 PCI-E DX10.0 GRAPHICS CARD WITH TV OUT + 2000MHZ MEMORY CLOCK' My current one, which I only bought last year, is a Gainward BLISS 7800GS+ AP 512MB. I have no idea which is best, I am using the computer as a gaming PC, so I was wondering if I should just use my old card or get one of the three, and if so which one? Many thanks Rob
