I was thinking of selling my R9-280x Dual X to get the Toxic version do you think its worth it or its just a waste of money? I was planning of also getting the new R9-290 but my budget can only get me the reference model...what do you think guys is the best option for me....thanks for the time reading! BTW i only game at 1080p single monitor also I would like to ask if AC4 isnt the fully optimized on the PC?
