Just want some opinions on dual vs tri sli from people that ran it. I currently am running 2 gtx 285's in sli and have been thinking of getting a third. I have run sli all the way back to the 7800gt's,8800 gts g92, and gtx 260 but never tri.from the few reviews I have found it does not benefit that much o go the third at 400.00 for the card.
