True but don't forget, as of last I heard the performance is still nerfed regardless of your system. Hell Look at how it is for TotalBiscuit, and he has a Titan Dual SLI configuration..
That looks awful. I checked out the Steam forums before making the switch to PC though. It sounds like the most recent patch finally got the performance issues straightened out for most people. I wouldn't know myself because I'm still downloading the 50GB installation file.
To be honest, I think I would have rather had Rogue than Unity because I liked the pirate setting in Black Flag. Not only that but it doesn't seem to be plagued by all the issues Unity has. Only the PS3/360 version was included in this sale though and I no longer have those systems hooked up.
