Hey all, thought I'd hit up the gpu experts with my scenario and see what you all had to offer for advice. I just ordered up a gtx 680 mac edition from evga for my 2009 Mac Pro. There's a feeble gt120 on there already. I was thinking about selling it until I realized I only get 2,560 x 1,600 over dual link divi out of that new card. I have a 27 inch Cinema Display that uses the mini display port on the gt120. Would it be ok if I just keep the gt120 in there or am I gonna need to pick up a couple extra cables or power supply? Thanks for any advice.
