Hi everyone... Going absolutely crazy here with this video card stuff. I was looking at the GTX 680, then started researching other cards, 770, 780ti, 680, titan, 980, etc. etc. and my head is almost about to explode! I therefore narrowed my choices.. I just picked up a 2010 5,1 Mac Pro with a single 3.2ghz processor and 5770. Im going to add a SSD and upgrade the video card. I am either going to get a GTX 680 mac edition, or there's a GTX 980 super clocked (EVGA) nearby me for a great great price. However, I want it to be fully compatible and can't find any information/guides on how to flash a card like this. Do any exist? I would be fine flashing it myself if someone has already written a guide Thanks in advance!
