OK, this don't make sense. You buy a mobo with a Nvidia chipset, but get an ATI graphics card. You do realise that with the Nvidia chipset that the board is optimised to understand nVidia driver code, and can be used to optimise reaction time in getting the stuff to the card, in order to ensure that the bandwidth etc is properly used. Put an ATI card in there and you're back to standard generic capability of the board, and the throughput on the bus is wasted. But not to worry dude. You'd only really notice those optimizations if you were running Nvidia SLI. However, with ATI, you're not going to see that. And I'm sure you're aware that ATI's Crossfire won't work on that board. Early SLI boards it would, but Nvidia hardcode that the board doesn't support it now. You may be lucky, but I suggest that if you do go dual graphics card, move back to NVidia, or try find a board with an ATI Crossfire chipset. (Good luck). Those are usually going to be Intel boards.
