amd 7970 ghz ed vs gtx 770 for triple monitor setup

[Samuel Filiatrault]

Like the title says, I would like to know which would perform the best in a 1080p triple monitor setup. I know an SLI or Crossfirex setup is ideal but i can't afford one. Thanks in advance for the help.

p.s. Games I plan on playing on this setup are Farcry 3, skyrim, BF3, MW3, LoL (not demanding I know), Batman AC, and assassins creed 3.

Farcry, bf3 would be down in the 30fps range, skyrim might be worse with the high texture pack or other mods. Both cards are about equal.
