I have two R9-270x's in Crossfire (ASUS Direct CU II's to be exact)
Now with Games they Run Buttery Smooth with Exceptions of Some Games Like Skyrim Modded to hell. Tomb Raider, Crysis 3 and Shadow Warrior (Reboot) and older games there is some screen tearing but its rarely noticeable.
this was a My Console Killer so i Built a Crossfire System for $1250 at the time.
but i didn't think problems with crossfire were this much of a headache.
For Example Skyrim has a Retarded ton of issues with crossfire with ENB Settings. the game is TOO bright or TOO Dark and the DOF blurrs the game until i disable crossfire and it looks perfect.
Crysis has Occasional Screen Tearing but its Rarely noticeable.
will An Upgrade to an R9-290 Outperform this and should i do it? cause i dont want to sacrifice my performance but i want to go with a Single GPU cause of the headaches with crossfire.
Mantle and True Audio is important to me. at least right now after hearing so much from CES Coverage from Linus, Logan and Everyone.
