My 7870 2gb (stock), i7 920 @3.6ghz and 8gb ddr3 is averaging 35fps, would say usually around 40fps at 1080p, original settings preset.
If anything, i don't find this game requiring much hardware at all, 2012 medium hardware does the job rather admirably. GPU requirements seem to go up when going for ultra settings though, like usual.
I'm also positively surprised reading this, the game doesn't even officially support the HD 7870, and an 8+ year old GPU series is probably low priority for AMD's driver team too.
