what would be better? lets say that cost is not a factor for shits and giggles. if you have a 280x would it be worth crossfiring it or would it be better to just get a 780TI? is the extra power draw, heat and any other problems that come with crossfiring worth a crossfire set up or would you be better off with one single powerful GPU. ive read that the hassle of crossfiring is not worth it.
