Alright all, Thinking of going single GPU for my Second build but struggling to come up with the right outcome. Title says it all and price factor isn't relevant as the Gigabyte R9 290X Windforce 3x OC is $775 in Australia and the Gigabyte GTX 780Ti is $779 over here. I want to be using this card for 3D work and playing games like crysis 3 on ultra without any problems. My other PC has a 7990 and it's great and maxes out everything, Just this is too close for me to decide. I am a AMD Fanboy and hoping that the AMD card is better but I just wanted to know what is actually better overall?
