I put 2 980ti's in my rig and started seeing some graphics issues, so i checked in my bios and it said that the system was running one of the cards at 8x. i would like to know if this is normal because all accounts i have seen is that it was running 16. a little help would be appreciated. i had to move the cards to sot 2 and 4 to get them to run both at 16x and it makes my computer run a lot hotter because the cards are so close.
