He can't go for SLi he has an MSI 790FX GD70, the same board as myself and its crossfire only. A single Nvidia card will work fine in this board by the way, I am using a Nvidia GTX275 and it's been just peachy.
I knew that... I don't know why I forgot. This computer has been sitting idle for so long I forgot what it's features were. I guess I'll just have to stick with the 250 until I can save up for a nice ATI card.
