[QUOTE=MiRai;350642]DX11 is a viable option in the drop-down menu of WoW's Graphics Options while running a GTX 260. I only know this
because I have 2 sitting in my closet. If a card doesn't support DX11 at all (even through emulation) then that drop-
down menu will be completely darkened out (unavailable).

This must have been a recent change. I positively remember looking at that option when i was running 2 pc's and the slave pc having gtx280's in sli, the option was greyed out. i jst turned that box on and now its viable. i apologize for the mis-information
