Adding a second GTX780 to Aurora ALX

 

With 875w PS, might be enough power

 

1. EXACT matching card. Pretty sure nVidia SLI requires everything matching (memory, clock-speed, etc.). So, another Dell-OEM if other is. Another exact eVGA-780, etc.

 

2. Possibly. There is not much room for cooling with divider plate right there. Those are big-powerful-hot cards (when maxed). Also, some newer cards vent into case instead of out the back. Might have to remove shroud or add extra fans.

 

All that said ... Aurora ALX is MiniATX ... works better with "single card solution: (like you have now).
