the DFI Lanparty UT nF4 Ultra D & nF4 Sli-D are fairly similar boards, the only thing to me that makes the nF4 Sli-DR stand out is the dual raid which the other 2 dont have.
all things considered i dont really think there is a hell of alot in it unless you were planning on running sli or dual raid.
i'd go with the nF4 Sli-D, its the middle priced of the 3 and gives the option of sli in the future.
imo the major drawback of these boards is the awful colour scheme.
any1 seen these under UV? more than likely they look alot nicer
stock dfi boards.
