Thinking of getting another 285 board and sli my current set up. Does it make sense or should I just bite the bullet and spend 500 on a new video card. If so which board do you recommend? Another related question what advantage is 16x and 16x over 8x and 8x. Wondering if I should swap out the board while under 30 days. Currently have a Gigabyte GA-790XTA-UD4.
