You could crossfire the two 550ti cards. I would make sure to set them both two the same clocks though (one might be running at a higher frequency than the other. In this case overclock the lower frequency card.) Just make sure your fans are spinning fast enough and monitor your temps and power draw. I hope that helped
Thanks so much! Now I've just got to order me a second vid card! Firefall the game is amazing and I'm sure it'll be even better on ultra high Thanks again to everyone who replied so quickly!
