Hi I'm building a new rig and these are the options. They are the same price. Which one should I get I'm playing at 1080p and maybe 5760x1080 in the future. AMD is supposed to update the drivers to make crossfire better.
At 1080p a single HD 7970 GHz or a single GTX 780 should be sufficient. You shouldn't need to CrossFireX. But if you plan to play at 5760x1080 resolution, then I would pick the HD 7970 GHz CrossFireX over a single GTX 780. Even though CrossFireX is still problematic right now.
