Hi guys, I am probably being thick as I am definately not techincaly minded. I bought another ati radeon x800 to go on my asus a8n sli deluxe main board thinking i could make use of the sli, having found that neither card seems to have a slot for the little connector thing that came with the mainboard I am wondering if i have two cards that are not sli compatible? Does anyone know? I installed the second card after swapping the dual video card board round to dual video instead of single. I plugged an extra power lead into the socket next to the top gfx card on the mainboard, the computer boots up, works for about 3 mins and then crashes. Please someone tell me if I am wasting my time and need to buy two sli compatible cards.
